Product price matrix for OpenCart

Project Description:
We are after a product price matrix for our new print website; we will be using Opencart 1.5.3.

We will need to be able to edit the prices without having to load each product to change the prices, our idea is to have 500+ business card templates (products) using the price matrix. This way if we were to change a price, this will automatically update all the prices linked to that price matrix.

To see an example of how we would like this to work, please go to http://bit.ly/SSFHOM

Also, to see an example of what we would need in the price matrix, please down our PDF http://bit.ly/UiD2Sw . I have also came across a script what would have worked, but it’s only for Magento, to see the script please go to http://bit.ly/dsiZhu

Every product we do will need its own price matrix. For example we do A7, A6, A5, A4, A3 and DL flyers, A4 letterheads, DL comp slips, business cards and folded business cards. So we would need to be able to add more when needed, so we can then match up to a selected product.

Any ideas are welcome.
