Cashback website design/creation

The requested project is to design and create a website that should function very similarly to [login to view URL] and CashCrate.com. Specifically, it should allow users to earn money for doing trial offers or making purchases through the website. Users should have the ability to search and sort for products based on a number of different criteria: product type, retailer name, price, payout (amount the user can earn), etc. There will be a member’s area where members can login and view how much they have earned in 2 areas: 1. Earnings from offers the member has completed. 2. Earnings from referrals The website should be able to track referrals that members make up to two tiers. Referral income will be paid out as a percentage of how much the referral member earns from completed offers at the website. This percentage should be able to increase when the original member earns a certain amount from completed offers. There are many referral software packages available for purchase on the internet that can do this task. If one of these can be implemented with the website, this would be preferred. I would like to avoid having to program such a referral/affiliate program from scratch if possible. The website should be programmed in a way so that member’s earnings will be paid to a specified PayPal account each month once they have reached a threshold (i.e. $50). On the backend of the website, I should be able to add or change offers at anytime without additional programming. I would like to have an administrative area created that will allow me to add, change, delete offers or offer payout amounts. This should be a fairly user friendly area, such as an html form. This will be a frequently changing website with new offers all the time; it should be made fairly quick and easy to make these changes. The look and feel of the website will need to be created as well as a logo. Overall, the projected website will have a very similar look, feel, and function to [login to view URL] and ebates.com. Please bid accordingly. Thanks
