Shopping cart customization - already have the files, want changes

The site design has been done and need some changes in admin and product pages, here's my beta site: [login to view URL] 1) top margin for the site needs to be 0. Here's the link to the picture: [login to view URL] I think it just needs to be recut without the white space on the top 2) Create thumbnail upload and a main upload for pics. Right now 1 image is used for the thumbnail and main picture a) Thumbnail parameter is perfect. Here's a link to the page: [login to view URL];category_id=8 b) For the main picture, dimensions should be no greater than 450 x 400. Here's an example of a page I'm referencing: [login to view URL] 3) a) When I upload more than one picture, they should not go below each other. Please check the link above on how it should look(thumbnails on the side and a window opens when clicked) b) I want all of the thumbnails to show up on the admin edit product page. Not just the first image and a delete option for each thumbnail(if thumbnail gets deleted, the main picture also gets deleted). 4) An option to add drop down menu and a sub drop down menu for admin section(up to 20 items per menu). The drop down options will also show up in the order reports/history. Link reference: [login to view URL] 5) A way to backup the database every 3 days. I need someone that can communicate clearly and able to help me setup a gateway and merchant account. I need this done by 4/28/07.
