oscommerce mods needed

I hope you can help me. I've had 2 coders flake on me already. Need some custom mods for my online store: 1. I need a way of offering a "store credit" to my downloadable material. It wouldn't be an unlimited downloads, but would give the customer a fixed number of number of downloads per month, so i would need to keep track of their downloads and whether a product is being purchased or is being requested as part of a store credit. (I imagine something like a gift voucher but I am charging them each month for it.) I need to be able to limit the subscription to certain categories (or products if I can do it at that level) I think this would be a tweak of the current credit and gift voucher contribution since what I need is a functionality somewhere between the gift certificate and the gift voucher) 2. I need a way of letting people add products to their cart more than one at a time. I am imagining a list like the category listing of products, but with a checkbox beside the names and then you could add all of the checked items into the shopping cart at once. I know there are issues if there are more than one "option" per product, but if I keep only one option per product, then maybe it could be done? It has to work with download products. ie pass the download attribute along to the shopping cart. Smaller stuff needed: 1. javascript validation of username to filter out capital letters (CAPS ON) on logon. 2. javascript validation of the product quantity in the cart if over 1 per item. (most of our stuff is download and they would only buy one) I would want a warning to pop up and they could click OK to acknowledge that they are buying more than one. 3. Need to be able to view the subcategories and their icons when I click on a category (just as the category box shows all the category icons on the mainpage) ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
