Deliver useful landing pages, websites and small automations. Find projects on CrowdWorks, package services on Coconala, and earn repeat work through testing and clear instructions.
Estimate earnings and hourly pay ↓Studio Toriumi's public projects provide a basis for testing web and automation services. That is an assessment of the work on display. The bilingual sites, information collection and scheduled updates, and browser tools in the portfolio show what can be built. Personal projects and paid client work are different kinds of evidence: this page does not claim completed commissions or achieved earnings.
Evidence: This portal's Japanese and English pages, plus browser interfaces such as the communication template tool.
First service: Fix mobile layout, spacing, buttons or copy on one existing page. Agree on the specific changes and supported browsers first.
Follow-up work: Improve another page, replace campaign content or handle monthly updates.
Evidence: Public information collection and scheduled update projects such as BCI WATCH.
First service: A small workflow with defined inputs and outputs: clean a CSV, aggregate a public API or produce a recurring report. Build a personal demo first for any untested environment, including Google Apps Script.
Follow-up work: Add data fields, failure alerts or operational support.
Evidence: The sites built with Workers and D1, and mobile app projects.
First service: A prototype or feature with a limited number of screens and data fields. Quote discovery separately from implementation when authentication, payments or integrations expand the scope.
Follow-up work: Production implementation after validation, maintenance and handover.
| Channel | How to use it | Fees and practical considerations |
|---|---|---|
| CrowdWorks | Sort listings by newest first. Search for landing page fixes, website updates, Python automation or manuals within work you can verify. | 20% on the first ¥100,000, 10% on the portion over ¥100,000 up to ¥200,000, and 5% above ¥200,000. Consumption tax is added to the fee. Official fees ↗ |
| Coconala | Offer a defined result, such as fixing three mobile layout issues. State the scope, revisions, required materials, deadline and extras. | 22%, including tax, for standard text-based services. Phone and video chat services have separate terms. Official seller guide ↗ |
| Lancers | Compare web and workflow improvement projects. Include communication, setup support and maintenance when judging the scope. | The freelancer fee is 16.5%, including tax. A lower fee alone does not make work easier to win. Official FAQ ↗ |
| Own site and referrals | New enquiries through your own publishing or referrals. Build evidence of your work, clear explanations and trusted recommendations. | Even with no marketplace fee, marketing, contracts, invoicing and payments take time and may cost money. Do not move clients met on a platform outside it. |
Check the budget, available materials, deadline, client reviews and payment status, AI permissions, and what repeat work would actually involve. Being first to apply does not guarantee an advantage.
Briefly show one relevant personal project, the first questions to resolve, the deliverables, draft date and acceptance process. Avoid sending the same generic proposal in bulk.
Do not produce a complete deliverable as an unpaid test. Use a small paid trial with defined scope and acceptance criteria. Treat possible repeat work as a possibility, not a guaranteed order.
These few examples are not market-rate statistics or evidence of our earnings. The ¥44,000 landing page listing was closed when checked; listing status can change.
A listing published September 7, 2026 requested static HTML and mobile support, offered ¥44,000 including tax, set a one-week deadline and mentioned repeat work. The estimated amount after platform fees alone is ¥34,320. Profitability depends on supplied copy and design, revisions and total hours.
A listing published September 10, 2026 offered ¥300 for a selection test plus ¥2,700 for production. Even the full ¥3,000 leaves an estimated ¥2,340 after platform fees. Over two total hours, that is ¥1,170 per hour before expenses. “Repeat work available” is not enough to make a project worthwhile.
For automation, a Power Automate Desktop project for PDF processing listed a ¥50,000–¥100,000 budget and requested setup support and ongoing improvements. An advertised budget is not profit. Listing status and displayed details can change.
A ¥50,000 project is not automatically profitable because you use AI. On CrowdWorks, an estimated ¥39,000 after platform fees leaves ¥36,000 after ¥3,000 in expenses. If sales, meetings, revisions and testing take 20 hours, that is ¥1,800 per hour. At 10 hours, it is ¥3,600.
Calculations run on your device. Inputs are neither stored nor transmitted. The CrowdWorks estimate assumes a fixed-price contract and uses tiered fees plus 10% consumption tax on the fee; standard Coconala services use 22%, and Lancers uses 16.5%. The estimated total fee is rounded to the nearest yen. Withholding, income taxes, bank transfer fees and payment processing fees are excluded. Actual amounts may differ by contract type and rounding; confirm them on the platform's quote screen. Allocate expenses such as APIs, paid AI tools, hosting and assets to the project.
| Scenario | Sales | After expenses, before income taxes | Total hours → hourly earnings |
|---|---|---|---|
| No projects won in the first month | ¥0 | A loss if you incur expenses | Sales time is also unpaid |
| One ¥50,000 CrowdWorks project | ¥50,000 | ¥36,000 (¥3,000 expenses) | 20 hours → ¥1,800 |
| Two ¥50,000 CW projects + three ¥10,000 maintenance contracts | ¥130,000 | ¥95,400 (22% on each contract; ¥6,000 expenses) | 34 hours → about ¥2,806 |
Where the platform fee is 22%, a useful price floor is (target hourly earnings × total hours + expenses) ÷ 0.78. A ¥3,000 hourly target, 10 total hours and ¥3,000 in expenses give approximately ¥42,308. If the scope grows, adjust the price, scope or deadline.
“80%” describes an early draft that makes the direction clear. It does not mean delivering with agreed requirements missing. For a fast turnaround, narrow the scope and schedule the review before starting.
Document the purpose, target pages, supplied materials, inputs and outputs, supported environment, deliverables, revisions, acceptance criteria, AI permissions and extra charges. Start production once payment is funded and the required materials are ready.
Agree on timing based on availability and materials. Label the preview “for review, not yet accepted” and show the main screens and behavior. Do not run real payments or use live data in a prototype.
Check broken links, empty or invalid inputs, form submission, duplicate actions, permissions, API failures and narrow screens. For automation, check failure handling, stopping and rerunning, duplicates and backups. Record why any test does not apply.
Include source files, setup steps, a short walkthrough video or illustrated guide, and known limitations. Publish to production after client acceptance. Keep secret values out of documentation and transfer them through an agreed secure method.
Agree on a period for fixes within the original scope. Quote new features, updates and maintenance separately. Define contact hours, a monthly work limit and incident support coverage.
Build a collection of knowledge and components you are allowed to reuse. Feed each project's problem, fix and verification back into your skills notes, checklist and estimating process. Learn from the structure, effort and mistakes in past examples without copying client deliverables or paid templates without permission.
The problem, what you built, what you tested, total time and the next improvement. Label personal projects clearly and never invent results or sales.
With the client's permission, explain improvements through screenshots, an article or a short video. Without permission, create your own demo with fictional data. Let your published work attract new enquiries.
At handover, ask about tasks that recur each month. Suggest maintenance only for useful work such as content updates, reporting or error checks. Avoid unnecessary monthly subscriptions.
You can begin with an existing computer, editor and free tiers to build samples and test demand. There is no need to buy courses or multiple AI subscriptions first. Production APIs, domains, hosting, assets and maintenance may still cost money. Check free-tier limits and commercial-use terms, then agree whether ongoing costs are included in your price or paid by the client.
AI can help with drafts, starter code, test ideas and manual outlines. A person remains responsible for requirements, rights, confidentiality, behavior and delivery. Before entering client data into AI, confirm permission and the environment being used. The CrowdWorks AI policy also calls for advance communication and meeting the agreed quality standard.
Focus on a limited landing page fix and a small automation. Produce a walkthrough, test results and a one-page guide, then define each offer and its minimum price.
Aim for five individually considered proposals in total. Prepare a Coconala service with clear quoting conditions. Do not send the template above unchanged in bulk.
Track draft turnaround, revisions, all working time and the amount received. If no project is won, review the proposal, samples and target projects.
Use around 15 well-matched proposals in total as a practical cap for the experiment. Compare response rate, contracts, effective hourly earnings and repeat enquiries. If there is no response, change the offer and target client rather than relying only on lower prices.
The first goal is one profitable project you can repeat, before a monthly income target. Use existing project experience to test sales and delivery on a small scale, then focus on the work whose numbers make sense.
