190026 CashBack Script

I'm looking for a ready-built cashback script. I'm not looking to spend money to have a site built from scratch, but rather a script someone has already made. I also don't need design, just the script. This should be a fast transaction for someone that has done cashback sites in the past. I don't need any exclusive rights or anything like that. Again as I want to keep this low cost. Script does need to be un-encrypted and 100% open-source. A script that a programmer has used over and over again is what I'm looking for. I've seen 100+ cashback project's posted on all the freelancer sites so I know they are out there. Please contact me with your demo and login information so I can browse over your script.
