Posting publicly gets you volume, and volume is the wrong problem when you are hiring one person and have no recruiting process. The best first hires almost always come from a warm channel.
In rough order of hit rate
- People you have already worked with — subcontractors, collaborators, former colleagues.
- Referrals from people whose work you respect, asked specifically rather than broadcast.
- Communities where the work is visible: Slack groups, forums, open-source, portfolios.
- Marketplaces, for well-defined project work you can evaluate quickly.
- Public job posts — last, and only with time to filter properly.
When you ask for referrals, ask precisely. "Know anyone good?" gets nothing; "Who is the best person you have worked with at turning messy notes into publishable posts?" gets names.
Write the ad for one person
Include the real range, the real hours, the actual work, and what will be hard about it. Being specific about the downsides filters better than any screening question and attracts people who want that job rather than any job.
Try it
List ten people you already know who could do this work or know someone who can. Send five specific messages this week. Do that before you write a job post.
