Ask HN: Hiring a Mentor/Teacher

Has anyone successfully hired a mentor/teacher to help them build a real-world project? If so, how did you find the right person? Are platforms like CodementorX or Toptal worth it, or is there a better way (like posting on HN)? A bit more info about what I'm hoping to do: My background is on the business side of things, but I have an intermediate JS background and I've been working to learn React through a handful of tutorials (Wes Bos, etc). I've learned a lot, but now I want to take it to the next level. I'd like to hire a developer who can act as both an engineering lead as well as a mentor to me in building a real-world application (basically a web version of some Desktop software that I already have an existing customer base for). Ideally we would be working with React on the frontend and Node/Graphql/Postgres (via Prisma) on the backend, since this is the stack I want to learn. In addition to actively writing code, the right person would help guide project architecture, plan sprints, review my code, and provide feedback.
