Check with U-haul, they usually have a list of movers that are independent of u-haul. My buddy rented a 26ft u-haul truck in the Riverside area and asked if I would help, I told him I would supervise but he needed to get some young backs. He called u-haul and they told him to look on their website, one of the options is for movers. A wide range of prices. A father and son crew came out and charged him $300.00 for 4 hours. The crew did a great job, finished in under 4 hours and he tipped them $100.00, best money spent.
Good Luck.
