Memory-game with highscore / leaderboard

I am looking for someone who has already created an online memory card game with leaderboard and would be willing to adapt it to a new design. Since we do not have the time or budget to come up with all the required functions and the general layout, we are only looking for a solution that is ready-made and can be adapted to our new content. Important: Please only contact us if you have already created a memory-game with highscore and are are able to provide a link to such. Any proposals without link will be ignored, also no flash please. Thank you!
