need Oscommerce experts

Hi, We need on the current oscommerce built site sundrugstore[dot]com replaced with new oscommerce version downloaded from oscommerce[dot]com and installed on sundrugstore[dot]com replaced from the old one but keeping the same look and template and product url (we dont want to change product url***). We need all errors fixed and tested with full functionality. Features that need to be re-coded are: 1. We have three payment processors installed, one of them is using MySQL database when storing customer's order information the other two are not storing database information so we need to log on payment processor's site and verify all payments and orders. 2. We need to have ability to see all orders made with any of these three payment processors through ADMIN of oscommerce. 3. We have bought an affiliate script and installed on sundrugstore, but we need to haace afiliate signup page on home page of sundrugstore[dot]com. 4. There's an error when adding new products it cannot be stored in database, after we installed two boxes and separated categories. 5. There is an option from ADMIN of sundrugstore[dot]com to print all orders on stickers, but since we installed a contribution problem orders it doesn't pull the orders from ORDERS table so we need this enabled again. We need all orders from ORDERS table from database and for all 3 payment processors. All must be first installed on testing server and then test all after you upload on sundrugstore[dot]com sever. sundrugstore[dot]com must ne after installing on testing server fully functional without any errors. Any suggestion from you welcommed. Thanks, Arman
