PC,
Go online to UShip. Have used them before and very safe, trustworthy, and reliable. It's kinda like ebay where different LTL Carriers and Agents Bid on your shipment. Never had any negative experience or issue with them or the Carriers who win.
Small fees and when all said and done, much cheaper than the Usual Suspects. The transaction runs through UShip so the Carrier or their Agent never see your financial info or card numbers and they don't get the money released to them until the job is done to your satisfaction.
