The only reason why investors would be interested in investing is if your games were actually attractive to the players and if your site made money. Right now you have a concept of making money, no actual money is made yet.

This is the point you will have to get across to your potential investors, if your games are that good, then you can easily start making money from the first day of your launch. I just don't think you're investable yet.

You should also consider moving this thread to Project development or any other appropriate section where asking for investment is common. Over here you will only find gamblers mostly.
