The upshot is that most operators have insurance requirements which mean that you are unemployable for most tasks until you have at least 500 hours. Your best bet would be part time work doing pleasure flying (in which case, I hope you have another career on which to fall back) or get the extra rating to become an instructor (again, part time). You will have to be prepared to go anywhere in the country if not the world. To get the hours, best bet - join the services; you're young enough.
Otherwise, it will not just be determination and passion you will need but also a lot of money!!!
There have been numerous threads on this very issue and there was a sticky - (Heliport, please can we have the training sticky back?)

However, things may pick up in the future and we may return to the times when the offshore operators were recruiting fresh CPLs as co-pilots but these days may be far off.
All the best
