In the US, no, as you are being paid to do the flying. Though there are certain instances in which you could perform the operation a certain number of times without it being considered commercial ops.
Key point, are you being paid to fly it? Then I would believe it's not kosher.
If you perfrom other duties and are not being paid to perform the flights, not receiving comphensation for it, then I believe a private could suffice.
Of course, I have no idea of how the european rules apply, sorry.
My question, you don't have a CPL, but you have the type rating for the 206?
(US you need a type rating for anything turbine or over certain gross weight, a private here could get a type rating in a 206, but likely wouldn't spend the $$$ on it)
