Sure. I am the founder of a YC company that originally did a Fantasy Sports for money product. While not an attorney, I did spend tens of thousands on them and learned a lot about applicable law.

My advice of course is to do the same if you haven't already. I'll be happy to give you my impressions but I'm no substitute for a lawyer who understands the ins and outs of your product. I can at least recommend a good one in the field of gaming law.
