317457 zen cart attributes

In zen cart we can make a product 'call for price' but we can't make an attribute. So we need a skilled zen cart programmer to help us out. An example we have a product called Alfalfa Leaf and the attributes would be Powder and Cut. Let's say we had the powder in stock but we didn't have the Cut in stock. So we would still want a price next to the powder and let the customer check out but the Cut we want an email for price and availability form to show up like: [login to view URL] (scroll down to aloe powder and you will see their link) or [login to view URL] (click on the notify link) To recap in the zen cart attributes admin page we need to be able to check a box that makes an attribute 'call for price' link show and not be able to checkout. and if they click the link take it to the new form they can fill out to be notified. Also the current call for for price link we'd want linked to the new form also. This is a live site so please only skilled zen cart programmers bid. Once finished we'll also need to know what files were changed so we can copy them over to a few different sites. So we'll need great comments on all files changed.
