I really think you will be better off with a Longranger for this type of work. It will cost you more to purchase, but not a lot more to operate. I flew this type of operation in the tropics for 18 months with a Jetranger, and with more than 3 people you end up with no room for baggage. An L-3 or L-4 would be ideal. Nicer ride in the 206L as well, with a little bit more speed.
