What this implies is that the more money people have, the better justice they can afford. Justice is not afforded or bought in our current system. Yes, the rich have unusually light sentences, but they still stand in the same courts and have to answer to the same authority. It's not perfect, but it's better, I believe, than what you're suggesting.
I believe a free-market court system will degrade into, like I said, a more-money-wins system. Here's a scenario:
Company A runs a clean, respectable justice service. You cannot buy your way out of being announced guilty, and you cannot buy guilt onto another person. Company B allows you to spend more money to achieve more justice. Which court would you pick? If you're poor, A. If you're rich, B. Result? B gets more money, B buys A. Now the only court left is a money-buys-justice one. Does this system work?
