integrate card reader into oscommerce gateway system

I have several projects for a skilled oscommerce developer on a highly customized version of oscommerce, currently used for full blown retail ecommerce, and also as the in-store commerce solution instead of a cash register. The first project is to retain the current oscommerce functionality (inventory, pricing, catalog features, etc.) and to integrate a mini swipe card reader so the system, via a browser and connection to the instore PC recognizes it as data input into the current payment gateway process, for customers who purchase items in the store via credit card. The gateway is cybersource and we accept mastercard, visa and american express. You can see the current functionality at [login to view URL] of the existing cart. Requirements are: [login to view URL] oscommerce experience, 2. A fully tested solution and post project support, with guarantees, and upload of the appropriate scripts and version to our test site first, then live site when signed off by QA. I also require oscommerce development references from customers. This is a relatively simple API script for magtek readers (or I will take other suggested card swipe readers if you already have software code).
