The trend in expediting is nearly always Owner/Operator leased to a carrier as an independent contractor. There are, however, lots of companys with several trucks that also lease their trucks to the same carriers. Many of these fleet owners employ drivers but they are typically independent contractors themselves and not an employee of the fleet owner.
I suspect you want to cut out the middle man (fleet owner) and be an employer of an expedite carrier. The only one that comes to mind is a company called Pitt Express whose owner is a member here on EO under the screen name of Teacel Check him out at
