Where can you get a hand truck repaired?

This is more than just a minor repair and it doesn't have anything to do with tires. My daughters boyfriend was helping us move and had his dad's hand truck. He forgot and left it laying across the toung of the traier and vehicle. We forgot it was there and left, dragging the handtruck along. The metal support plate across the bottom broke into two pieces and the wheels broke off (not flat). I feel like I need to help him pay for the repairs, but I don't know what kind of shop to take it to!
