I guess the best option right now could be some sort of eosbet route where you just pay people dividends somehow. I mean I know you are zero house rake but with that it is almost impossible to get big funding, there is absolutely no way a smart investor go into zero house rake and hope the advertisements would be enough.

Or like many previously mentioned you could have an ICO and just distribute the earnings equally among the people who hold that coin, which could still be small but at least help out a bit.

Think of other ways to create funding aside from an investor, that seems far fetched right now but I am sure you could find other ways to gather funds, specially from community because people do not mind sending couple bucks to anywhere anyway and many people combine together could create a lot of money even though individually they look small.
