Total of items by Brand – cost to do ?

Thank you for providing this plugin.

What I am trying to achieve is to get a total number of products by brand.

a) a screen that lists the brands and gives total of product for each brand

b) a screen that has a selection box of brands and selecting a brand lists all products for that brand just like the product list. And the ability then to print that out as well as export.

Is that possible, can you do that for me and at what cost. ?

thanks
