Well first off this is a site for escorts and clients of escorts.

There is a FAQ for Newbies forum to your left.

And specific questions are more likely to get an answer.

Talk to a lady who has been in the sorts of businesses you are contemplating. Even if escorting isn't under consideration, there are people in this community who have done that sort of work and give you a heads-up about what you might face.

Search reviews for providers who are porn stars and call them. There are some veterans, like Cumisha Amado, who know the ropes and might even offer you a job (since she is now producing).
