Custom simple shopping cart tutoring/building

Hi, I'm looking for someone who is willing and able to SHOW me how to integrate an order form for MULTIPLE ebooks to purchase as you create it. I want the order form to add up the total for all selected ebooks, send it to payapl, and THEN redirect after a successful paypal payment to a DYNAMICALLY generated page showing links to the ebooks that were originally selected during purchase. So, for example, if they purchased ebook #2 and say #8, then only those links will appear on the download page. You and I will hook our computer screens up using GoToMeeting so that you can walk me through the steps as you build. Here's the order page I'm working on for a friend: [login to view URL] Thank you, Carl Contino
