Wordpress Affilliate plugin customization

We have a wordpress site and need to add the following. 1. Update our affiliate plugin so that instead of an affiliate giving out [login to view URL] as their affilaite link. we want our affiliates to give out their registered name such as [login to view URL] We want to create the link from their first and last name when we register them. 2. Our site needs a shopping cart that we can allow buyers to add a coupon code for discounts. We currently have a paypal button on the site and we want to change to a shopping cart . We would want to manage discount codes from the back end. To be considered for this project and future projects you need to do the following. 1. Start your bid with "instructions read" all other bids to be deleted. 2. If you place a bid, your bid amount is the amount we will pay if we accept you. Don't ask us what our budget is. We are always looking for a long term relationship. Hopefully that is with you.
