I used TYDEF Studios to do the post-production of an audiobook. I had a tight turnaround for a book and TYDEF came through. Tyrrell and Samantha are good at their craft, as well as the actual business side. The process is very streamlined and nothing had to be printed/scanned! The workflow is fairly simple depending on what you're getting. The proofing is spot-on and my audio doesn't have the over-processed sound. If you're looking for solid work and good business practices, this would be your place.
