I would suggest:
Something with 2 engines.
Something with relatively salt tolerant fuselage/components.
Something with world wide support.
Something with high tail rotor or a fenestrom.
Something with good maintenance schedules I.E. 100hr+ intervals
Make sure you have provision for reliable and 'beefy' ground power.
Good protection for machine when she is lashed to the heaving deck i.e. dome/bubble/extending canopy
Skids are more stable than wheels (especially castoring types)
So sounds like a EC135/145 or maybe a Agusta grand (if your likely itinary wont have issues with 50hr inspection interval!!!)
When would you like me to start??
