Flex/Java Social Role Playing Game for Facebook

I'm producing a **social role-playing-game** for **Facebook** that is similar in style to *Mafia Wars*: [login to view URL] The front end will be built in **Flex 4** and the backend will be built in **Java** and be hosted using **Google App Engine**. The game will also make extensive use of the **Facebook API** and will also have a few data management features I'm looking for a company or coder with expertise in all these areas to code the game from a detailed game design specification.
