Customize Aheadworks Shop by Brand magento extension

Hi, I would like to get the Aheadworks shop by brand extension ( [login to view URL] ) customized as per my requirements below. Currently the extension works in the following way: I have a brand called Port Royal. Now when i customer click on the brand name it takes them to the landing page of Port Royal where they can find all the products of that brand. Please check the following page [login to view URL] Now what i want to do is that the brand Port Royal has 5 Product ranges Prestige, Rural, Windsor, Rustic, Platinum. So i have these 5 product Attributes. Now when someone clicks on this brand name, it should take the customer to the brand page where they can see 5 Blocks ( Attributes ) for these 5 ranges WITH NO products visible on this page. Now when the customer clicks on one of the ranges, say Windsor, it should take them to a new page with all the products of that range only (Products with attribute WINDSOR). Note: You will not be working on the website, you will get the extension and you only customize it and give me the customized files to upload to my site. You will have to work on your local server with this extension.
