I'm guessing you mean the middle European semipro leagues?
A friend of mine who then played in Finnish 3rd tier received an offer from Belgium. Gear, apartment and 1300€ per month iirc. His factory job payed over 3k so needles to say he turned it down
but when you will be looking for a job in for example Romania, Croatia, Italy... there you will have bigger chance. And bigger money. Here in Slovakia is the situation a little bit crazy. Many teams have big money issues, but many of them are looking for old, above 30 Czech players. And they are not so cheap.
You'd pretty much have to be at least a pretty good AHL'er to be certain to make a good living playing hockey in Europe. There is a handfull of ECHL'ers who have made the bigger leagues in Europe but not many (mostly the ones in DEL). Then again if your goal is to make some of the lesser leagues (Italy, Great Britain and such) you don't necessarily have to be a junior star or even a really good ECHL'er. For example (if you're a forward) a PPG record from the OHL or 0.5 PPG from the ECHL should do. Although with stats like that you'd only get paid very little, as in McDonald's little.
