My father's shop does a standard brake job for $89.95 P+L, including new pads and turning the rotors (which he insists on having done as part of ALL brake jobs). His shop's among the CHEAPEST in the area on this particular job, though.
Expect a good (read: done correctly without taking shortcuts) brake job to run about a C-note to a buck-twenty, additional if you need to replace under-spec rotors or have tohave bearings repacked along with the brake work.
