For my car 200sx ser one rear caliper is $99 from advance auto, pads are $40 and rotors are I think $70 a piece so that's around $280 if you do it yourself it should only take an hour and a half at the max especially if you get the vacuum bleeder($20) and flare nut wrenches($11) at harbor freight tools, I just made the cheapest jack stands ever at home depot using cinderblocks and plywood $11 for 4 "stands" now that's a deal
