add on job for oscommerce

PLEASE only bid if you are osc expert as it is small job. The work to be carried out is to modify an os commerce site to perform functions that the current site does not currently perform. The functions must be accessible from the control panel so that the customer can run and maintain the site without having to get another developer involved. You can see there will be catagories on the left hand menu. When the customer clicks a category they must select a material. The material should be displayed as a thumbnail with a description of the material and a price. After clicking on the material it should go to a more descriptive page with a full explanation. The customer must be able to add more thumbnails and materials from the control panel. For roller blinds there must be a third option after selecting the material. The roller blinds have metal poles at the bottom and there are a few different types. The customer should be able to add the pole types themselves. When the customer has selected the blind, material and pole if necessary they must select from a dropdown box the size they require. After this the site must give the customer the option to buy online. Try to give unlimited thumbnails.
