Dont tell anyone you're a spanner swinger, they'll lock you up in a hangar and make you fix aeroplanes all day
You might need to look further afield, IE the Pacific islands. Your time looks about right to get a go with a mob flying as a BN2 driver or twin otter FO. Try Vanuatu (NZ instructor time is good too), Fiji, Solomons(be careful), Best of luck....
Keep banging on doors.
