DNN - Fix Catalook Shopping Cart

The requirements for fix this bug is quite straight forward. Our DNN shopping cart is not working properly. See the symtoms below: What happened? Well, actually, a previous developer we hired seem to make things worse. It was actually working before and we hired a developer to make some pricing/coupon adjustments. But after he started it began to not work and now we have no coupons and also no credit card processing. For this job there is only one task, which is to fix credit card processing. > When clicking on "process order" it now crashes with some paypal error. > To many results are listed for shippers so we dont need 5 UPS shipping options just about 3 (overnight, ground, 2nd day) Notes: > We use paypal pro for the gateway We are looking to hire someone for this project, and it will lead to more projects. I prefer to have one good and reliable developer instead of many unreliable ones. Good, neat, and timely work receives a bonus.
