OsCommerce Payment Module

Interested in someone creating a custom payment module for Oscommerce to interface with [login to view URL], which uses proxypay3 as its system. There is a specification file that explains the method, at the systems manufacturer site, = [login to view URL] I believe I could achieve the connection myself but I simply dont have the time to do it, however since I have both knowledge of oscommerce and php I could assist in many ways also.
