Shop near me is $275 for an overhaul:
> We’ll take apart your bike piece by piece, overhaul the bearing systems and put it together again. Then we’ll perform a full-tune up, install new brake and shifting cables if needed, and give it a thorough cleaning. It’ll ride like new.

I always tell them to just replace anything you’d replace if it was your bike. Generally after 3 years there’s something they replace like rebuilding a wheel or something. I’ve always been very happy with the service and value because other than light cleaning and oiling I don’t put any effort into maintaining my bike.
The mechanic (same guy I’ve seen for the past decade) told me (in a backhanded compliment sort of way), “This is really a testament to how well a bike can hold up with no maintenance other than an overhaul every few years.”
