BTW, removing the motor and retracting the piston using a hand or power tool is very easy. Only thing to remember is to plug the connector to the motor back in.
I hear you about the labor though, it may take you about an hour or hour and half max 2 hrs but if labor is included and they are using close to OEM parts, might just let a trusted indy handle it. If its someone you haven't dealt with before, with the car as well put together as yours, you might want to give it a personal touch
(BTW, I'd recommend EBC red stuff or Yellow Stuff for pads and rotors either OEM or Zimmerman.. )
