I am interested in doing hot shot work. I live in Dallas Texas and I am interested in making runs maybe to local and or surrounding cities and states. I am also looing to purchase a trailer up to 16ft. Where do I start? What are other profitable businesses I may get into. I purchased this truck (white) with the intent of conducting business and working for myself.

You can lease your truck to a hotshot company like acme trucking, ace trucking etc.. If you want do hotshot with a trailer you should buy at least a 32ft gooseneck to make worth your while. Oilfield hotshot is the most popular right now.
