It's not a stupid question. The simplest is to look for a "business lawyer" and then ask them about their experiences with businesses like yours

But also, don't overestimate what a lawyer is going to do. They're not going to make your docs legitimate, but they will spend as much time as you want to pay for working on them and telling you the risks.

They _will_ frequently be able to get you started with docs like that, though. If they've done the work before they'll have a ready to go draft for you.
