I am in the process of setting up a small affiliate/referal scheme. Much like that of www [dot] forfree4u [dot] com.

I am unfortunately not greatest when it comes to coding and would be in need of a small client area with tha ability to add "credits" for referals. Could someone make any suggestions as to whether there are any scripts out there in existance that can do this for me, or how easy it would be for someone to code from scratch?
