Congratulations on what sounds like a great event - and also on being appreciated with a medal!
The organisation which over the years has proven to be energetic and most reliable is Friends of Poland, a charity based in London, UK, which helps Polish families in Kazachstan, Ukraine and Lithuania. We send our donations through them, and have total confidence in their honesty ( and experience). As soon as I get their bank account number I will email you.
Once more thank you for your energy,and enterprising spirit,
