I don't book them but I load a lot of trucks, from broker
www.JTcompanyinc.com is one of the better ones, Ask for Anita shes the GM.
What you have is a specialty load high end car, but also a LTL (less then truck load) so you need to be flexible if they can add yours on to another partial you might get a better rate.
You can also use something like Uship.com, they all kind of use the same method of finding drivers for loads.
