Selling bbpress css upgrades through WooCoomerce

Hi,

First time posting, so please correct me where i am wrong. I am trying to figure out how i would get a plugin or begin to understand how to program a specific product in a woocommerce store.

The product involves a CSS or search return boost for members, lasting 1 week. The boost should be applied to their three (3) allowed posts in bbpress for the period of time, and then revert back after.

I have searched the web for answers but am unsure if im approaching it with the correct terms or if it even exists already.

Thankyou
