Cashback Site Needed Making

I need basically a copy, or very similar design to netcashback . co . uk and/or linemypocket . co . uk i need the script installed and into a basic design, which could be changed at a later date. Need site to look quite proffesional Im only interested in serious people who can get this done quite quickly. Budget is very small as there is one BIG difference. Unlike most cashback sites where money goes back to the people who buy thru the links, money from here will go to a charity of there choice. So remember 100% of profits made from the site will go to charity, so thats why my budget is so low. Thanks
