Need ProdCart programmer for express order form

We will be using ProductCart for selling to our wholesale customers. Since wholesale customers often already know the item numbers and quantities they need to order when restocking, we don't want them to have to go browse/search each item and add it to their cart. We need a custom "express order entry" form with 20-30 lines where they can key an an item number in one field, and a quantity in the second field. Upon submission, the form should validate that the SKUs are valid active item numbers, place the items/qtys in the cart, and take the user to the cart viewing page to verify and complete their order.
