A flash game - can be based on existing one

I need a piece of music added to a flash game - ideally you would already have the game done - so the project would be easy - I just wanted a specific piece of music adding and maybe a little customisation. This is to promor the single of an UK band on a small indie label - we have done a retro 'nintendo' version of one of their song. Ideally the game would be a bit retro/old school - can be very simple - would be good it it had a high score facility I'm not looking for a custom game from scrat - just someone to spend an hour/two changing something they've already done. Happy to carry an ad for you as part of the game - and obviously you would have the version with the music on as part of your portfolio. The band are Wire Jesus [login to view URL] and the retro game version of a song is available at [login to view URL] Thanks Jim Bowes
