Or......
You could seek out a willing private owner of a floated helicopter and talk them into doing this as a private flight (cost sharing only allowed, you can't pay the full rate).
Imersion suit and raft still a good idea
Floated R44, EC120, Jet Ranger (if fuel available at the destination) possible
Fly there doors on - in the warm. Refuel, take the doors off and fly the picture sortie. Land and refuel, refit the doors and return.
Simples!
(If you can find a willing owner)
