Not an expert, just a driver.
But to me it looks suspiciously like a solution (helicopter) looking for a problem to solve.
FW are almost always the cheaper option, so why use a helicopter? And is a boat ride not a more economically viable option than a short helicopter ride?
As has been said before, get an expert to look at it. First and foremost to prevent you from falling into the trap of getting helicopters when the market is not really there.
To a man with a hammer, every problem looks like a nail..but it could be an expensive mistake.
