I think I'm a little doubtful that the OP found Highroller, outside of who knows maybe yes.
We never know until he confirms it, but it's worth a try he has a review site so he can offer the best casino for both of them to be on good terms, this thread will show up on the internet and if there are high rollers who wants profit sharing this might well be the thread and the guy he is looking for, I think all the other casino reviews has a special offer on their review page but this is the only thread I've seen one is looking for a revenue sharing plan.
Anyway good luck to OP in finding a high roller.
