APUG certainly isn't restriced to people who do their own work.
I think what Ian meant is that the scanning and digital output is generally off topic for APUG. That stuff is open discussion for the hybrid sister site dpug.org.
The costs are one reason most do their own b&W. The pricing you're seeing may be oriented to people looking for high-end custom work.
One alternative for you may be to hook up with other members in your area who might be willing to do some processing for you. You could try posting a note in the Canadian regional forum.
