You could seek out a willing private owner of a floated helicopter and talk them into doing this as a private flight
It is exactly this sort of mentality that causes AOC operations to struggle. People spend good money gaining & maintaining an AOC, likewise pilots who gain their CPL/ATPL. Low level Permissions from the CAA to make this legal are also required. Why would any PPL owner want to 'cost share' for a commercial photographic shoot?
It is also the reason that accidents happen. PPL's are by definition not qualified to the same level. Photography involves low/slow or hovering at levels inside the avoid curve. If there was an accident, do you think that the insurance would cover anything, knowing that this was in essence a commercial flight? Personal injury claims, 3rd party claims, aircraft damage claims?
