I think you will have a hard time running this as a "business" because this implies you want to live off of your "assumed" winnings. Online casinos are profitable for the right player, but it's hard and in the event you are good enough at it, some will either fraudulently deny your winnings outright (will just give your deposit back), or they will pay you, but you'll get locked out and a message saying "we do not believe you are a profitable player for us, therefore we are exercising our right to deny your patronage at our casino".....
CM can help you with legitimite complaints when you submit a PAB (and you'll probably need this). It also has a ton of smart members who can give you techniqal advice. As far as APing goes, there are other forums more suited for providing that kind of advice (just Google search it!).
PS: Personally I find sports wagering to be bad bets. House edge of 10-15%....No thank you! If your from North America, maybe try 5 Dimes casino (they offer better bonuses to Canadians and American players too I think).
