Cost me approximately $450 per hour in labor. PVC and one economy sink drain at less than $20; the disposal provided. Your plumber you sent was a skilled tradesman and gentleman. All debris including old disposal and pvc traps completely removed from my property. Except for the exorbanant price I am very pleased with the skill and workmanship provided. Based on estimate, $925 expected adjustment when work was preformed in two hours. Price, $450.00/hr is out of line.
