Ask the same question on rotorheads and you'll get the hard, gritty truth.
Unless you really, really want to fly helicopters and have such a desire that your whole ambition revolves around it, then you might scratch a part-time living. The rotary job world is very sparse at the moment.
If you need to ask the question, then I would suggest that your rotary desires are not enough to get through so go fixed wing; I believe the opportunities, whilst not common, are slightly more easy to get.
