Work / Want to move BACK to Poland from Canada, need your help [5]

Alright, long story short on my life, I was born in Poland (Jelenia Gora) and I moved to Canada when I was 5, I went through the whole education system here, I am fluent in Polish, English and French. However , I have been thinking lately about moving back to Poland for some time, possibly permanent. I realize I probably have a much better life in Canada , but my whole family is there (aside from parents / brother) and I just have some questions.

Such as , average income? (Not in Warszawa / Krakow) or better yet, how many zlotys a month do you think I'd need to be able to maintain a 1 bedroom apartment and car and live fairly comfortably, ( if you can factor in obvious gas prices, car insurances , food, etc etc. would be greatly appreciated.)

Assuming I made 4000-5000 zlotychs a month and had no spouse / children to support, am I looking fairly good? AGAIN ANY ADVICE / comments appreciated.
