Looking for a widget plugin to automatically upload and link PDFs

I’m building a site for a client and there are 4 widgets at the bottom on each page.

Each widget will have 1-2 sentences about a product model and a link to 2-3 PDF brochures.

I’m building the site and the client is managing all of the content. There’s 70+ pages on the site so I’m trying to find an easy way to basically drag a text widget with a file uploader attached to it.

Anyone know of anything like that or a better solution? I’d love to avoid manually adding 200+ links.
