Product Configuration Utility for OSCommerce

We have a couple retail websites that utilize OSCommerce. We have customized OSCommerce quite a bit, but we need to ability to have "configurable" products on the site. For instance, selling rackmount servers, we have standard, prepacked configurations where server type, processor speed, amt of RAM, hard drive configurations, etc are all static. I would like the ability to make these types of products user configurable. Starting with a base product, we want customers to be able to make configuration selections using either radio buttons, or drop down menus. There will need to be some simple logic in place to validate the user's configurations, and prompt the user is they have made an invalid product configuration, so they can correct it. Finally, once the product is configured, including the base product and all the add-on products the user has chosen that comprise his/her chosen configuration, we need the ability to pass the line item product SKU's which compose the configured product into the OSCommerce shopping basket, so the order can be processed. ## 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.
