This is not a job for a part time pilot.
There is no sightseeing pilot in this kind of business. The companies involved do the full range of helicopter business like external load, heliskiing, rescue with quick changes between the tasks. It's sometimes very tricky to operate in mountains and deep snow and therefore they want only very experienced pilots. And also of course experienced in the operation area.
A lot of well experienced pilots are waiting for a job cause the market is very small. Only very few operators.
For Switzerland you need additionally a special mountain rating.
The normal way to get such a job is to clean the hangar a few years mixed with in difficulty increasing pilot work and to learn the way they handle the things from the beginning.
