Davy,
Look at it from the viewpoint of a potential employer. With 100 hrs (and not much of that P1) what sort of work do you think an employer would think you were safe and competent to do? In a single turbine, it is going to be single pilot, so you would be in charge of the commercial flight.[Incidentally, I think Whirlygig is probably right that you would need more than 100 hours to get a JAA commercial licence. I am gratefully out of touch with that sort of information these days].
Others have outlined some of the difficulties of getting the training done. There are also issues with sending a very low time pilot solo on a turbine during training.
Even if an employer could be convinced to give you a job, insurance would be a problem too, probably.
In the end it is a case of supply and demand. In any normal industry a company would train its staff, but aviation, especially heles is different. They can get away without, so they do.
There will be very few opportunities for such a pilot to work: in summary, as close to no chance at all of getting a job as makes no difference.
The problem these days is that because the various regulators have f****d the system up there is no sensible route to progressing from licence issue. It may not have produced the best instruction (arguably), but the pre-JAR "hours building route" via PPL instructor gave someone who was keen a fighting chance.
Depending upon the market, there is a possibility of offshore co-pilot, but generally, the offshore operators are looking for an IR (which is lots more money). They have had their fingers burned with training non-IR holders.
