Exp Dr considering O/O

Hello any/all, I have about 14 yrs exp with the past year and a half in car hauling. I also recently obtained my doubles, tanker and hazmat endorsements and am considering going on my own. I live in central Tx and it seems like there is opportunity in just about every kind of freight but I'm leaning on sticking with car hauling since I have experience not only in hauling but am also familiar with the financial aspect of it. I do understand the concepts of a business plan and understand the risks involved. So I'm here looking for any useful info and advice thanks!
