Coupio PayPal Coupon Site

I own a website called <[login to view URL]> It is a subscription-based business that allows online sellers (site owners) and eBay sellers to create custom coded Paypal discount coupons to promote their auction items or, website products and services. I need help with enhancing certain site functions that my customers are asking for that I do not know how to write the code for. This is a fully functional and hosted site/business with active customers. The OS is Linux. The files are PHP. More specifically, what I'd like to do is the following: 1. Allow sellers to toggle between creating Paypal coupons for auction listings such as eBay, Yahoo, etc. and for their privately owned ecommerce websites. 2. Allow sellers to create coupons for various types of products and/or services specific to either an item/product number or description and serve as a tracking tool. 3. Another enhancement needed along with #2 above is to allow sellers to create their coupons not only with item specific numbers or descriptions, but also the inclusion of the gross (non-discounted) item cost. 4. I'm having some functionality problems as well. (2) the systen doesn't appear to be deleting inactive user accounts who have cancelled and to whom I may have issued a refund. 5. Lastly, the data base does not seem to be logging and sorting user accounts properly and customers are experiencing difficulty logging in. That's basically about it. Give it some thought. Visit the site <http://www/[login to view URL]> and let me know what you think.
