Freight Broker Entry Level

Hi,

I'm trying to get information on how to enter the freight broker world. I have a carrier authority, but I'm not currently operational. I inherited a truck from my father, and since he was the one in the field, I'm trying to gain more knowledge of the trucking world. While getting the truck operational, I figured I could learn more about the industry and add a little revenue to my current funds through Freight Brokering. I received my certificate through DAT, but now I'm running into issues with finding positions. Being new to the field, I don't have a book of business, which is being requested by a lot of the companies I've come across.
