If only 2 people going in say a Robinson R44 Raven II like my wife and I did then it's no more than 300 per person or they have to charge a higher charter rate and use a larger helicopter I think. In response to the answer below about no more than 1000 lbs. in a helicopter. In the Robinson R44 Raven II we flew in it rated at 700 pounds if it's full of fuel as well. They do have larger helicopters as well. Not sure what other models but something they might have would be maybe a Bell 407 single turbine helicopter that seats a pilot plus 5 to 6 others and if it's full of fuel it can handle 1142 pounds (or 1998pounds BEFORE adding fuel, so half full gives you 1570 pounds useful load).
