Well you can either post it in this board,
Project Development or
Auctions.
And maybe some angel investors might be interested on someone will offer you a partnership. I guess the most important question is how 'provably fair' is your system. I know that the more money you bet the higher chances of winning, however, what if two players bet the same amount? which one is going to win base on your rule?
I think it's not about who bets a larger amount of money, but about placing a random number (like in roulette, or who will be closer to the drawn number). However, I would also like OP to explain it, because I am also not sure why the amounts given in the example are different?
