I need 4 things done on my zen cart website with custom template installed:
1. implement multiple product images on this custom template
2. add a quantity box to product listing pages for adding multiple products to cart
3. create/implment a module/function to allow customers to pre-order products that are not yet in stock. The pre-order will not charge shipping fees and will only authorize the credit card.
4. make small layout changes to various pages such as aligning boxes and line breaks, etc.
