Work / Work in Katowice -it's an industrial city and life in rather difficult there (?) [3]

Hello everyone!
I hope someone will be able to help me out...
I'm Greek, 23 years old and I have graduated from Athens university with a BA in English Language+Literature.
I have worked in a bookshop for 4 years and did almost everything there (from orders to dealing with clients and from cleaning to setting the display window!). I have also worked in a language center and taught English to young/teen students. I am computer literate (I have also taught Microsoft Office) and I speak French, Italian and of course my mother tongue, Greek. My knowledge in Polish is basic, I would not imagine writing about it in my CV...

I have participated in many seminars and conferences related to Special Education. I'm really good with children.
The thing is, I really need to find a job in Katowice (or somewhere near, but I'll be living in Katowice) starting September or October...

I've been told that it's an industrial city and life in rather difficult there... in terms of finding a dignified job, house etc... I hope it's not as bad as I hear..

I don't know what I could do in a country where I don't speak the local language, and it's really ironic since my mother is Polish!! (no, she's staying in Greece...)

Any help regarding working opportunities will be highly appreciated!!
Thank you very very much*
