I'll suggest you DON'T hire an attorney until you have determined if you have a viable business model first. You will have very little risk initially because you will be virtually anonymous.
As someone who has created a few MLM opportunites, which are highly scrutinized by the FTC, I've discovered that even if you have dotted all your I's and crossed all your T's, most startups can't survive an FTC challenge simply because it costs tens of thousands if not hundreds of thousands to defend yourself...even if you win.
So my advice to you is to move forward using common sense, don't make any outrageous claims you can't support.
Once you have a proven business model (profitable) then spend the money to protect your investment.
Private message me if you have any questions, I'll be happy to share some of my experiences with you.
