Improve & Rewrite MMORPG

I have a complete and working version of a Mafia style game for facebook. What I need done is for the script to be rewrote as a standalone site (an easy task for a skilled programmer). Also the sign-in system will implement an easily integrated OpenID platform (about an hours work). On top of the rewrite you will be adding new features that will implement ajax and javascript (or similar) to make the game more interactive as well as add more features to fit the idea that I have. In summary you will be taking an existing php script and improving upon it. The winning bidder will be required to sign a NDA. All bids that show you have not read the listing itself will be ignored. Please address this posting directly to be considered!
