well, just do more research. plenty stuff in the 'stickies' and other threads. use search.
European IR is not cheap, even single engine.
very limited jobs with just fresh CPL, honestly. It's due to insurance and fact that you don't have that much experience with few hundred hours.
Just look at the recent R44 crashes in Brazil. Totally avoidable. Anyone with 500hrs total heli in Brazil would go and fly to oil righs as copilot for pretty good money. Those flying piston in Brazil are either owners or low time charter chaps. I presume so.
Well, JAR/EASA FCL dictates 300TT heli to START FI rating. Some countries like Sweden, UK, Romania, Switzerland etc, adopted 250hrs as 'happy compromise' to make things easier. So it's not easy/cheap to get there after all the training if self funded. So go for it and keep saving. Try to get as much R44 time as possible, not just R22.
I don't know Polish job market, but you may want to check options as copilot on larget stuff, with whatever minimum training sponsored by company.
That's enough for now. You have to do your research.
