Trochilidae
What IR do you have if no twin rating? Was it done on the 206.
If offshore was your objective, have you been and visited the 3 companies or do you just post/email your CV. If you havn't then maybe you could organise a trip and see them all, and personally hand them your CV, it stands you out from the rest. I heard that one of them was looking for pilots, and with an IR you are much better placed than I was.
Hope things turn out okay for you and never give up.
