If you are flexible, an extremely profitable (and legally more solid) alternative will rely on the dynamics of Bitcoin. If you award me the project, I can setup a gambling website whose sole currency is the universal electronic currency of Bitcoin. I can setup a server with the code for the gambling game, I can market it for you on forums, and I will be available as tech support when problems arise. If you are not aware of Bitcoin's purpose or market, I can educate you on it, regardless if I am awarded or not. I look forward to working with you.
