Start a Casino
Casino payments are normally made through credit cards and accepting credit cards nowadays is not a very difficult thing to do. There are free merchant services accounts through which you also can start accepting credit cards.
A good business if you have a nice infrastructure in place is to open an online casino. There is not a lot which you need at the start. You will need a software which you can get made or can buy from the market. Also you can become a betting site wherein you can accept bets, etc.
There is also scope to join hands with big guys like Prima poker and get your members to play with theirs.
