Well, first off, unless your audience knows you, you are opening a "can of worms" by posting a file that could hold malicious code. You might want to rethink the uploading format bit. Better to use PDFs, unless you need the files to be editable.
Are you allowing users to upload or do you want to do it just as the admin?
You could create a field called "Docs" and put a link to the file, after you place it on your server.
Or you may want to use an upload/download manager and just link to the file that way.
The more information, the better the answers ;-)
