Categories on OSCommerce Front / Home page

Hello, This is for OSC 2.3. I need the following done: 1. Display images of all main categories on frontpage 2. List all sub-categories of the main categories right beneath its main category's image (as described in point 1) 3. Image for main category in point 1 and links for all sub-categories must be clickable. i.e. if a user clicks the image for the main category, he will be redirected to the main category page, same goes for sub-categories, however, no image for sub-category is required - just the link which can be clicked to reach that subcategorys page. I would need this done on a basic OSC 2.3 install. The deliverable would include live demo and the code with instructions for me to make the changes on my store. Please bid. Thanks!
