setting up api

Hello My name is Abraham Lieberman. We currently are working on an online stre taht needs to be upgraded. My Partner who is a designer makes great site on network solutions ecommerce system. Unfortunatly network solutions does not seem to be able to interface with any api for pulling and sending data. so we need to come up with a soution. I need someone who can implement an api from a drop shipping company for an ecommerce site. one suggestion my be to configure a site using zencart or oscommerce and implementing the instructions from the drop shippers api and then export it into the network solution site or work with my designer let him draw the layout for the pages a images and you interface it with the shopping cart. I have ADS API Instructions, and Data Feed Documentation. The drop shipping program includes inventory status and item ids necessary for order fulfillment and submission, but full data feeds are also available to use to populate the site. . If you have any other ideas how to make this work propose it and set your bid. There is a potential for a lot more work if you can interface with my partner (the designer)and work well together, because there are several other custom sites that we will give you.
