Reasonable timeframe for repairs? Five minutes to six weeks. Five minutes was last November/December, when I needed help getting a pedal off (time to rebuild the pedal bearings, and it was frozen to the crank). Six weeks was 8-10 years ago, when my bottom bracket wouldn't come out. Soak it in penetrating oil, whack it, try to unscrew it, repeat. (Then two weeks later I went through the same thing with my backup bike!) Both were pretty reasonable.

Glad to hear you're talking to the bike shop. That's how you'll get things ironed out.
