FWIW, the R66 will do this mission no sweat.
- OGE hover at max. gross and 25°C is 6800ft.
- Max. gross is 2700lb. A well equipped ship (air conditioning, etc.) empty might be, say, 1340lb empty. Full fuel is 493lb, cargo as specified is 120lb, that leaves 747lb for people. Leave just a little bit of fuel on the ground and you'll have 800lb available in cabin and still have 300NM range.
Obviously cabin comfort can't match the EC120, but it won't be struggling. Glass cockpit, autopilot, AC all available. Needs a lot less hangar space, too. I wouldn't spec. floats, too heavy for your mission requirements. A super high-spec machine might reach 1360lbs empty, but you can spec the Lithium battery and that'll remove 35lbs.
