472909 Develop e-commerce site

A plastic card company requires the implementation of an online ecommerce site. Our site uses asp and MS access for our current client data entry, very simple. There are currently no e-commerce facilities on our web site. In summary customers will come to the web site and add features to their cards, each feature may or may not add to the cost, this cost will be immediately visible to the user as they add/remove features. Once the customer has finalized the features they would proceed to an order submission process. They should then have the ability to pay right away or later using a credit card or pay pal. I have very detailed specifications for the successful bidder, there is approx. 4-6 weeks work at 8 hours per day.
