Salt water, Silica frac sand in Mississippi

I am told that hauling salt water and frac sand pay very well, is this true? Can anyone tell me if there are any companies in Mississippi doing this? I am getting ready to go to ACE to finish my CDL schooling and I want to find something paying better than .30 or .40 cents per mile. Can anyone suggest what I should consider hauling to make the best money?

(My trucking experience has been hauling hot shot with a 1 ton and hauling rv trailers for Horizon Transport)

Any suggestions and advice is greatly appreciated.

Thanks

 

Thanks for responding, can I ask who the company was and were they in Mississippi or deliver in MS.
