3rd Party Trucking Anybody?

Has anyone here ever bought trucks to put to work at a company and hired your own driver's to drive them? I have been talking to ACME truck lines about it and they are all for it, but I am not sure after I split the money up on a 70% lease there will be much left over. Or atleast not enough to make it worth while. I drive a truck now for a pipeline company but I was just thinking for investment purposes. Let me know what you think about this deal if you have done it and if you work or know of someone that works for ACME if the trucks there are grossing enough.
