Bounty: A zero-confirm modified bitcoind

[vintosalgos223]

I am looking for someone that can modify bitcoind for me to process 0-confirm bets for a casino site. As far as I understand there will be 3 changes,

1. An RPC call that will take a specific TX and pay back coins to the original sender using sender's coins combined with additional funds (from a separate source) if amount to return is larger than initial bet.
2. Allow bitcoind to send funds that are zero confirmed.
3. Additional security measures that you can think of.

Please PM me with a quote of what type of coin this project will take to get done. I'm eager to move swiftly on this as the site and PHP front-end is complete.
