Need expert on osCommerce to modify and cleanup existing store. The store is up and running but it has some bugs. I need the following things to be fixed or implemented: - Customers will have a choice to chose paypal before signing up, if so they will go straight to "confirm order". - Fix the 2checkout payment module. The details of purchase are not going through and customers are not returning from 2checkout. - Fix the customer orders module in admin. I can't access it or edit orders. - Modify front page. - Fix the specials feature. - Cleanup templates of "cartoonish" standard icons that came with OScommerce. - Modify/add links on header.
