I need a programmer who is very familiar with Zen Cart to develop 2 mods. One is an image upload which will be attached to a selected item in the cart. The other is a check box, which if checked will multiply 10 cents times the quantity of the specific item selected when adding to cart. These mods have to be configurable in the admin panel same as any other attribute associated with an item. This project is time sensitive and I need the mods completed within 2-3 days of the start date.
