"The shop" will turn the same bolts that you'd have to turn. However, they will be able to more accurately set the camber. Locate the lower control arm attachment points at the chassis frame. There will be two bolt heads with a cam that either pushes or pulls the arm inward or outward to set the camber. Look on both the front and rear side of each arm as they have two cams per side (front and rear - 4 total on car). I intend to elongate the slot (towards the center of the car) that the camber bolt slides in and out of to get a more negative camber than what I'm limited to now. Most places can adjust the alignment. I intend to do a rough adjustment on mine then take it in for an alignment to get maximum and equal negative camber on both sides (strip-only car).
