Modify php code to Image Gallery Maker software to have a custom CSS and a CMS

We are in need of someone to modify the open source of the following product: <[login to view URL]> ? ? We have purchased this software but the customizations that we are in need of are not available from within the programs options. You can obtain the source code from the file we have attached, install it and become familiar with it before bidding. It seems to be coded in PHP therefore the ideal person would have experience with PHP coding and possibly some simple javascript. We would like to add a css skin for it similar to the layout of [[login to view URL]][1] ? but with only 4-5 images per row rather then the 7 that they have on their site as they have in this example <[login to view URL]> The css skin should have all the left navigation menu as on [[login to view URL]][1]? where you can view by brands and categories and some type of navigation buttons on the top going left to right like this site does.? We just don’t need their exact tabs. We would like the ability to eventually have over 100,000 products entered into this product gallery.? Under each thumbnail, we would like to enter the retail price, the wholesale price and more information html link. We would like to have each thumbnail searchable by the product name as on this site. We would also like to have some type of CMS added to this system for the ability to control advertising on it. ? Thanks
