I think they are a broker, which means all they do is post the "haul" on a national board and wait for someone to say they want it. If the price sounds too good, it usually means you will wait a while, not always, but most of the time on cheap rates. The broker gets paid the same either way, normally about $200 and what's left goes to the carrier. You may already know all of that, but some here might not. Good luck, hope it goes well for you.
