Affiliate software for Osc

Create a tailor-made affiliate marketing system for an online store. We have an oscommerce store, with products on already. We want to create an affiliation software that allows people to advertise our website on theirs with a small banner - members should be allowed to log in to their account and see exactly how much they are earning. Each product should be able to be set at different commissions. The commission should be paid directly into the members paypal account. State clearly your [login to view URL] around US$100-300 (we choose the cheapest price and the most capable candidate). If you have any questions, please ask. If you have examples of affiliate programs you have set up personally, please include the name of the website you've done that for, as it will help our decision.
