OsCommerce Payment set-up (NoChex, Paypal)

Hi I have a customised Oscommerce website which currently has the following Payment options - * NoChex - the APC module version * Velocity Merchant customised CC payment module Velocity is currently disabled and can be ignored and I currently only use the Nochex APC module which is working fine and correctly. I have now upgraded to NoChex Merchant feature and need to get it working - from what I can tell it requires a few changes of the URL call-back to the script or install of the Merchant APC module for OScommerce. I also now want add Paypal to the site and hence decided to let someone handle all these tasks at one go. Please bid only if you can show Oscommerce work and portfolio specially customisations that deal with Payments and shipping. When you bid PM me samples with specific details of what you did on the sample site. PM me for site url and thanks for looking and good luck
