Code to show Product Slideshow

I am looking for a coder to produce me three simple pieces of code. 1. 7 (or maybe 9) Random products to be shown as per picture code not the whole list. Products to change when screen refreshes. 2. Layout as shown with a text format arrangement. 3. New which will need the picture code enhancing - show 4 across screen with the title of the product below and a price which is contained in the file (including the ? sign) and all boxed like shown in the picture. I already have code written to do the existing functions but need someone to correct to provide these extra functions. All this information is taken from a .txt file which I export each time. You can see from the pictures the site which we will be doing the work on so I don't have to list it here for SEO purposes.
