We have a project that has already been started by a programmer, but due to unforeseen circumstances he wasn't able to finish the job. The goal is to have a shopping cart system that allow for user-determined pricing. The previous programmer was using PHP, jQuery, and the Zend framework. This project is on a tight deadline. We need someone who can dedicate 2-3 full days, possibly even continuing into the weekend so that the site is functional by Monday, February 23. Attached is the code developed thus far.
