I just replaced my rear rotors and pads for $40 for the rotors, and $50 for the ceramic low dust pads. To save you some time also the rear calipers require a special tool to screw the piston back in when you take the pads off instead of using a c-clamp.The brake tool also can be rented free from most autopart stores, or you can try to use a flat head like I did.

...To install the rotors just remove the wheel, the splash shield(2 bolts), and remaining bolts on the caliper that connect it to the rotor (minus the brake line bleeder bolt). Then when you remove the old and put on the new rotor, put the caliper back on, remove the two bolts on the top and bottom of the caliper.Then screw in the piston with the tool or screwdriver(exception front wheels use a c-clamp). Put the new pads in,put it all back the way you took it apart and enjoy.Also the front calipers dont have a splash shield.

P.S. Please do this yourself it only takes a newbie an hour and a half tops!, And a mechanic will probably charge you out the ass, not to mention you dont know what quality parts they would put on.
