I think the colonel probably ask the most important question.
"What are you doing in this business"?
Setting rates in your case is much more involved without knowing more than you posted. Do you have your own authority? Do you have the proper vehicle and load insurance? And in what amounts? Might depend on what a customer will let you haul.
What kind of freight are you hauling? Expedite, LTL, International, Government, Hazmat????
All of those will have a different rate structure. Origin of freight will affect the rate as well.
I could go on, but I believe based on your limited information, you need to take not a small step, but a very large one back and understand what you are jumping into.
Might sound a pessimistic, but I see a potential disaster on the horizon.
