Clone of Hacker browser game (Urgent!)

Hello, We are starting a new like game project like [login to view URL] We have created most of the artwork and we need a skilled developers to build the game engine and logic with exactly the same features of the current web browser game. Bidder should have a proven track record of developing a fully browser based MMOG or a project similar in nature to that. There is no restriction on the development language but the design of the application must be MVC compliant with clear inline documentation such as folder for language so it will be easy to translate the continent to other language easy!. This is a long term project and once it is deployed a yearly maintenance contract could be signed. GAF and Moneybookers pay only! Thank you
