OSCommerce Quantities for Product attributes

I'm working on a project for a client and I need to be able to enter a quantity for product attributes. If the quantity is 0 then the attribute should not show on the catalog side. For example, I sell shirts in 3 colors - blue, red, and yellow. I have 1 blue, 5 red, and 0 yellow. Yellow shirts should not show up as an option for the customer. I need to be able to enter the quantity for each attribute in the admin area from the product attributes section. There is a contribution that fits my needs exactly (Quantity for Product Attributes Mod) , but I don't have the skills to install it. I am also using Product Attributes - Option Type Feature, so the two need to be integrated flawlessly. I need this ASAP, preferably by today or early tomorrow. Payment will be made via Paypal after completion and testing. The budget is very low, so the lowest bid will probably win the project. There is a possibility for a long term relationship if I am pleased with the work. All work is confidential. You may not refer to the work as your own to anyone or place anything in your portfolio, website, etc. about this project.
