Oscommerce site completion

I need a very experienced oscommerce expert to finish my site. Here is the deal. The site was finished and completely functional with coupons/vouchers and multipics. Many items were added. Then we changed servers, and domain names. Well, either the person I hired (cannot find contact information) didn't move the correct tables or we just cannot find them. So first off, I need someone to look very well and see if the functional site is there and we are just not finding the files and set it up, OR if not, I need you to correct my errors in admin and get this site finished with multipics and coupon/vouchure contributions as well as the INFO SYSTEM contribution to allow me to add extra pages. I also need the pages to be SEO. I would also like the products there (the ones that come with the site) deleted. Also, on the credit card pages, I need you to add a place for the customer to put in there security code off of their credit card. Again the site must be fully functional. Lots of files I can see are stored and I would like the person to be able to go through them and see which ones you can add back into the site. Please ask if you have questions. This is a simple job for someone experienced. I would like to communicate via instant messenger to complete this assignment.
