Flash Game Required

I have a requirement for a flash game for my dating site. I have a few ideas of how it could work (based on my website's theme) but would appreciate some help with expanding on these ideas to make the game both fun and entertaining. I would like a score system, perhaps where a monthly prize could be awarded. Members would be able to submit their scores after logging in, whilst non-members could play the game and have an option to submit their score at the end if they agree to sign up. Please only bid if you have familiarity with flash games and integrating with php/mysql. Experience of what makes an addictive and fun game would also be ideal to get my ideas off the ground. Will explain more to interested bidders.
