PHP Shopping Cart Customization

I'm in the midst of a PHP shopping cart upgrade. I had my old version customized and the codes for the customization are still in the old version for reference. I know exactly what files needs to be edited so I can be of help, also. The new version has a little difference here and there, but not too much. I need someone who is familiar with shopping cart customization, JavaScript, PHP, MySQL database tables to be able to look at the old coding and make the appropriate tweaks in the new version. There are about 3 small projects here, which should not take long after reviewing the old coding. I need someone to make these changes ASAP as I would like to get this new version of the cart up in the next couple of days. Project descriptions: 1. In the new cart the products were transferred via database from the old store. There are a couple of minor issues that need to be resolved. The Image Alt Tags and Title Tags cannot be saved and the Meta Keywords cannot be saved. Also, the Edit HTML link does not work in the editing of products in the admin area. 2. Transferring the MySQL database of the orders and all of its content from the old store to the new. Some of the tables are not matching up so it is not displaying the orders correctly. The order database table needs tweaked to match the new store's, so I can transfer the order database smoothly. 3. On our One Page Checkout there are some default buttons. For Ex. (Continue button and Process Order button) These buttons need to be replaced with an customized button that we have created and work properly. 4. We need our template changed when tracking numbers are sent. At this moment it sends an invoice which our customers find a hard time reading and don't notice the tracking number at all. I would like to change the template so that it is easy to read the tracking number or put a message in the subject of the email like "Track Your Package". Here are the URLs for the old site and the new site's test server: [login to view URL] [login to view URL]~sweetper/ You can compare these two to see exactly what I was referring to.
