I have a site where people fill surveys and offers and receive virtual currency. Offers are from various vendors. I need someone that can configure my postback.php files to properly credit my users whenever they fill out an offer. The site is based off of a CPAlead script, so anyone with experience with this kind of script, please apply. My site is bumgamer.com and I would firstly like to connect offers from trialpay.com, superrewards.com and usamp.com. If all goes well, I will be adding more offers, so this would be ongoing work. Keywords: MySQL, PHP
