In any case, a lawyer is the one you should speak to, but bear in mind, it is illegal for a lawyer to advise you as to how to break the law, if that's what you have in mind.

Regarding taxes, etc., a CPA is what you may need.

If this involves escorting services, contact other providers on boards that are set up for that purpose.  They should be able to give you some good advice as to whom to see.

(still not a lawyer)

Contact some VERY experienced providers and ask them about the best lawyers in your area. Hire or retain the very best that you are able to afford. Without that you are a sitting duck and fucked top the HILT!  Good luck
