[Plugin Request] Looking for content delivery plugin

I’m looking for a plugin that will allow admins to upload files for a particular user.
When the user for a given role logs in, they will have option in the admin panel to see all files available to them. Clicking a link for a file will allow them to download that file.

I’m willing to develop a plugin that does this, but if there is an existing plugin that is similar that I can use or extend, I’d prefer to go that route first.

Thanks!
