Obuba Oscommerce Customizations

We have a list of customizations we need completed for our oscommerce website: 1. Our server does not currently have register_globals turned on, we need the site configured to turn it on. 2. We need a quick checkout package installed to reduce the number of steps taken by a customer to check out and to not require the customer to create an account. 3. We need a way to provide a coupon code and store credit for our customers. 4. As an order is taken we need to send this order to our order fulfillment company via an XML feed. 5. We need a method for our customers to download the articles we post to a pdf file or attach them to an email to send to a friend
