Amazon Webstore Template Re-Design

I have currently started an [login to view URL] Webstore: [login to view URL] I need the following redesigned to my current template: 1. This item pictures currently cannot be made larger in it's category. I need to be able to change the size of the images of the items in each category. 2. On the Products Page each item has a "Enlarge" button that has a Pop-Up picture. The current template does not allow the Pop-Up picture to be larger that the the one displayed on the "Products" page. I need them larger. 3. Web store does not seem to allow you to move the products around in each category. Is seems that if you add inventory and need to add an item but want it in a special place in the category that you can't move the item once it's there. I need to be able to move my products within a category. 4. I want to have the ability to have some of my products displayed in a subcategory only. It seems that the current template will only allow my items to be place on both the Category and the Sub-Category page. This honestly does not make sense and I need this changed. I need to keep my current home page and template if possible. Please contact me if you have Amazon WebStore experience.
