Only chance is if you're very lucky and know the right people. Otherwise your best bet is to get to 250 hours and do an FI rating.
Yes, the above is what most people do. Unless their timing is right and they get taken on by the North Sea companies. They gradually build their hours, get extra ratings etc, paying for a lot of it themselves. Some get lucky, or go abroad, or something. But not many.
There are just too many low hours CPLs. What happens when you get to 185 hours and get your freshly minted CPL? Bugger all, that's what. It sounds like a lot to you, but really, 185 hours is absolutely nothing. You simply do not have the experience to do very much. And why should any employer train you, pay for ratings etc, when there are plenty of qualified pilots around?
A lot of instructors enjoy their work, and aren't that bothered about doing anything else, at least not in a hurry. A lot of people would just rather be paid to fly helicopters in any capacity than do any other job. Does it make sense? No, not to most people. Only those for whom it makes perfect sense will do it. And as you can see, there are rather a lot of those. If it doesn't make sense to you, don't do it. There are more sensible ways to earn a living.
