I changed the brakes on my gf's car, 07 Elantra, and it was time consuming but very easy.
Shops were wanting $210 for each set, the auto stores were wanting $158 for each set, so I looked online and found the same break sets (rotors and pads) for $119 total with 2 day shipping.
Cost me a 6 pack to use an air compressor and some air tools.
Do it yourself if you can.
