UPS, FedEx, USPS, etc are good options.
Or, OP could check the boxes as excess baggage on OP's own flight to HNL. Assuming each box is 50lb or less, the first box (assuming a standard coach ticket) would cost $25, the second box $35, the third box $150, and boxes 4 through 7 (and up to 10) $200 each. Total $1,010. Any box heavier than 50 lb (and less than 70 lb) would be subject to an additional charge of $100, so OP would want to double check the weight of each box prior to check in at the airport.
OP probably already knows that USPS would charge about $97/box, total $679.
