I agree, that you have to be careful with this. That's why I am proposing a hard threshold. You have to give a person an exceptional amount of money, but then you are free (or at least more free) to negotiate a contract.

IT freelancers in Germany are hindered by regulation originally designed to prevent outsourcing of factory staff to the lowest bidder.
