28225 OS Commerce Experts only

I have a customer, who more or less needs everything OSCommerce offers... Primarily, the way new products are added and the product attributes system. This work is pretty much a mod in how the customer is going to see the attributes. The whole site is going to be constants as far as the attributes, there will be products and every product will have 4 attributes. 1. Product Color 2. Size (this will need to use a input box, and not attributes set in the admin. 3. Options and Materials (primarily accessories) 4. Other Options and Quantity (primarily the quantity is the concern here) Now the reason they are broken up into numbers like that, is because (unconventional to oscommerce default install), he would like each of those to be a page, and I can show you a live demo to qualified bidders. So a customer would view a product, and not see a add to cart, but the #1 attribute, they would hit next and bring them to a 2nd page with #2 attribute, etc etc. the rest of the oscommerce pacakge can be kept the way it is, as its PERFECT. You will not be inserting the products, this work is just to adjust a vanilla install of oscommerce in to working this way, and maybe installing a sample product to show it works I have tried to go a little high on the budget hoping, that I get a professional who can deliver before the end of the month. Please do not bid if you can not start somewhat immediately, and finish before 2 weeks (hopefully sooner)
