Design and Layout for ecommerce Site

Hi, I need a layout designed for a Cake e shop. Background: This site has 4 main categories - Wedding Cakes, Specialty Cakes, Fantasy Cakes, and Photo Cakes. Each main category can have multiple sub (n deep). Please keep this in mind when designing menus etc. The main areas I need focused on is the color scheme, easy to navigate, and the category layouts in the top menu and side bar should be attractive. Requirements: 1. Color scheme - birthday colors 2. Homepage - display 4 main categories laid out in an attractive manner. 3. Product Listing - lists all products for a chosen category. Have a small image, short description 4. Product Details - displays a image of the cake, description, available options (size, color, icing), price, add to cart button. 5. Cart page - up to you to design a clean page that matches the rest of the site 6. Top menu - Home | **Shop** | About Us | Sponsors | Login 7. Sub menu - Browse All | Wedding cakes | {+3 main categories} 1. Each sub menu will drop down to reveal their child items 8. Each page, except the home page and cart, should have a side bar that displays the categories in an attractive, easy to use manner. I will need the original PSD files when completed.
