Joomla phocadownload monetize

I have a website which provide download facility for visitors. I am using Phoca download ( Joomla component) for managing the download section. Site get somewhat between 50-100 downloads per day. So I was looking a way to monetize the click on download button like showing an ad(pop under preferred) when someone hits the download button. Need some guidance regarding the same.

Before starting the thread I have searched the forum using keyword" phoca download" but no success.

adfly or some kind of link method. But phoca dl may need to be scrapped unless you can serve a url.. Id say forget phoca and just use some kinda link ppc thing
