How to create a Wordpress Loop that loops through PDFs, but with thumbs and excerpts.

Hey guys,

I am trying to figure out if this is possible. I am including a screenshot of what I would like to build with Wordpress.

Basically, I need to be able to upload PDFs to a page, and loop through them, but attach an image and excerpt to each PDF separately, so when I loop through, the PDF has a nice thumb and excerpt and when you click on it, it links to the PDF.

Any ideas? Thanks!
