I'm going to suggest, when I was a contractor, like most of you JIT gave us a large head, making us think we really were special. In reality, was/are simply rolling warehouses.
Get involved with an organization the does in fact do some needed moves for customers and your rates will get there. Problem with many places, the skills, or interest just is not there in the dispatch or driving force to capitalize on the capacity you offer with your equipment. Therefor, you are being paid for what you run in your "warehouse".
