LiteCommerce modification

I have LiteCommerce installed on a server and need a few modifications: 1. On the home page (which loads from the templates section (skins/default/en/[login to view URL])) I have a set of hard-coded images that forms a picture. I'd like to have code there that randomly loads one out of 6 sets of pictures. 2. Again on the home page, I would like to have a rotating product (chosen randomly.) I want the thumbnail to display with the product name under (that links to the product) and a link to the category like "see more s." 3. I need some custom fields (5) added to the product table that can be used in the admin interface and import and export catalog. There is a post here on how to do it: [login to view URL] I already added them to admin/product/[login to view URL] and [login to view URL], but the module needs to be updated to get stored in the database. I set a lower budget on this project because if you have experience with this product, you can do these changes very quickly and easily.
