We have graphic artists that custom typeset the resumes manually. There are 2 revision rounds included in each purchase (additional revisions/edits/versions can be purchased) so there's back and forth with our artists.

You should mention his on your homepage. I assumed that the $99 got me a fill-in-the-blank Word template. Having a designer do the heavy lifting and polish sounds much more appealing. You could also easily upsell to editing and review too.

i'd say manually, since part of their job is to put the resumes together.

So it's basically just a specialized design agency.
