Reliable-PROVEN Groupon like script needed

We are starting a group buying coupon site like Groupon and wanted to see if anyone could give us a referral where to find a reliable-PROVEN Groupon like script. If possible we would like to take an existing script and modify it to meet our needs. We need a script that that is currently in use with at least 2-3 active – English URL’s (active- pending deals and transaction history). We need to be able to validate the usefulness of the script to complete our due diligence. Thanks in advance.
