$125 seems about right if you aren't supplying any materials and no drawers, doors or drawer fronts.
I would figure about 3 hours to do that cab as is and would price it at about $40 an hour. I would likely add about an hour or so because it is matched to the other cabs which should be worth something.
Obviously doors and drawers would add a bunch.
On estimating time I try to charge a fair rate on what I think it should take. I am slowly getting close to where I finish in about the time I think I should.
