Looking for an English speaking school for a 10 year old boy in Poland

I’ll be moving to Poland by the end of this year or the beginning of 2011, I have a 10 year old son who is fully bilingual in English and Spanish. I wonder if there is an English speaking school in Warsaw that it’s not too expensive. I’ve already visited the website of American School of Warsaw. It seems a wonderful school but, it’s not within my budget. I also want him to learn Polish. Hope anyone can help me. Thank you so much.

I don't know if those are okay but you can at least call them and ask where to go and where is right school because they know it best :)

If you can't afford the American school, next best is the British school. If you can't afford that, your only choice is the international European school: the others are certainly not recommended.

I will do that, Thank you so much Harry and Butterfly.
