| Self-updating site | ¥200k–500k | Like the WATCH sites above: collect from fixed sources daily and bake into a static site plus email. Designed to run at ¥0/month. |
| Research / long-form writing | ¥50k–200k | Written from primary sources, with evidence graded by strength. Cited, JA/EN available. |
| Consultation only | Free (30 min) | Whether what you want is feasible, and roughly what it would take. |
What I take on, and what I don't
- Good fit: build small, ship fast, leave you with something you can maintain, and keep running costs near zero.
- Poor fit: on-site work, large team projects, or high-volume rush orders. As a solo studio, most work happens weekday evenings and weekends.
- Declined: health claims that require asserting outcomes, projects with unclear copyright, and anything that requires publishing a real name or address.
