I agree with nickaix.
If he has access to free equipment and tools in some shop you might get in the $50-$60 range.
Otherwise the cost of a one of unit that takes three hours of a machinist with equipment, consumable tooling, utilities, floor space, raw material for gears and pins, insurance, scrap (units gone bad), etc. would easily get in the $200 for three hours. I think the $150 for the truck with the work completed was a fair price. I agree that having several in hand to work on should reduce the cost.
