New direction and Keeping Authority???

Asking for good companies or independents to sin on with. Would love to know who to contact to use my own authority in a different type of freight , but just don't know where to start acquiring jobs for such. in my area. I'm hoping i can keep my authority active . I have a freightliner and would like to find someone I can lease to using my authority . Maybe not , I'm out of Tulsa, ok and would then like some suggestion of good companies i can contact to lease to on percentage basis, thinking solelyowner operator my area to . I have a failing back surgery so have to leave flatbeds, any suggestion for lowest labor freight is what I have to search. Thinking dry bulk or reefer maybe, I don't feel if I put a lot into it I won't be able to do as well at van. but have no knowledge of ones in my area. My son actually will be keeping our authority to run hotshot business out of Oklahoma City. It just does take a lot of time and work driving and running the business . So I've realized sharing some work and profits. By signing on with someone legitimate can be a profitable deal. Just can't live with giving any away. Good customer base is no loss just a business investment . Thanks so much for any suggestions. Mike
