Trucking: hotshot light loads

Question
How can I find companies or car dealerships that are looking for someone to make deliverys on weekends

Answer
Find out how much your competition charges for doing the SAME thing.

Start calling / emailing dealers offering to do it for less ( to get your foot in the door).  Also, if there are any auto auctions in the area , see if you can get your name on a bulletin board there offering to haul.  If you can, advertise that you are available on short notice ( and than be available) and of how far you are willing to go distance wise.

You will need USDOT and MC authority to do this.  DOT for DOT purposes and MC because you will be considered a For Hire Carrier.
