Catch-22.

You need to hire today right now professional developers to get this done. One man working 12 h/day will not be able to do this. The funds may be locked up in escrow and inaccessible at this time. You need to borrow real money against it and pay for real developers immediately in order to get this done.  Every blunder is a black mark ever step of the way. We are at 3 now unless some real initiative to solving these problems is displayed nearly everyone will be so quick to dump this once it goes live, and never return, you can kiss this dream goodbye.
