ASP Checkout

Looking for a shopping cart checkout solution. We have the site and database all in place. All products have weights associated with them. Visitor comes to the site, clicks item, places them in the cart, ** <<<YOUR SOLUTION STARTS HERE>>>** Zip code is requested to provide estimated shipping,? site goes out to UPS? and USPS? and? returns **Fastest**? and **most? Economical** shipping options. Client chooses which option and then Checkout. They are asked to either login, create an account? or check out without creating an account. Billing, Shipping and Payment are requested all on one page along with cart total. Complete order and a conformation page is displayed. Basically the site will mirror the checkout on this site: [[login to view URL]][1] There is no payment gateway, data is recorded to a database, site owners log in via Admin and view orders and process Credit Cards manually. This may change in the future. Credit Card numbers are scrubbed automatically. The existing site already has an integrated UPS shipping calculator however most items on the site are small and light therefore we need to integrate with USPS as well. I think this would be easier to do from scratch than trying to patch it in. ## Deliverables Server is MICROSOFT and solution must be suited to this.
