To: OP
I am willing to offer escrow for this tournament in order to increase the odds of this happening. I am a chess fan myself, and this seems like fun, but seeing that you are of the "newbie" status, people will most likely not trust you. I am offering to hold the funds of this tournament, without releasing any payments until it is publicity determined who is the winner. I would then send the prize money, and then the 24$ to you (minus $1 escrow fee).
