PHP script Customization NEW

Script Customization: Am using a script called motivated marketing system (MMS) The script handle membership, affiliate tracking and payment processing through clickbank , paypal etc. I am having a couple of problem with the script and also need some simple customization. 1) Customize script to handle Paydotcom payment processing or add a module. The script has an inbuilt clickbank, paypal, [login to view URL] payment modules. However it is also supposed to handle any other payment processer using an affiliate tracking script. But after the payment is made, and the member click on download product, the link does not work I need this to be fixed or perhaps add a separate module for paydotcom. 2) In the members area I would like to add a default FREE products where any new member will get access to the download link Requirements: Knows PHP very well If am happy with your work, i will need your services for other scripts. Time: The quicker you can deliver the customization the better Bid: when you place your bid, please post or pm me some background about u. Also let me know if u have used mms before. This would be an advantage but not a perequisite. Budget : Please only bid if you could complete the project within my budget $30-100
