In the UK at least, freelancing on a TBM 700/C206/PC12 is a bit of a non-starter I think. The reason for this is that at present they are not allowed to operated under IFR for public transport. (I know JAA are approving them, but the CAA is as usual dragging its feet).
If you are employed as a freelance pilot to fly a trip in such an aircraft, it immediately becomes public transport as you are being paid directly for your plioting services. This is different to working for a company which also uses you to fly their aircraft (eg corporate). This is then a private flight and is not restricted by the SE IFR rules.
Confused? Everyone else is!
