looking for preferably a part-time job (Brussels)

Hi,
I will be living in Brussels in a few months. I'm a teacher of English as a second language in Turkey. I have worked at several schools in Turkey. I wonder if there are some suitable job opportunities for me to work in Brussels. If it is possible, I may teach Turkish as I'm a native Turkish. Or maybe working at schools as a volunteer.

Another thing I'd like to know is that; I want to improve my French there. I would like to get some information about courses.
I will be pleased if someone gives me some information about these cases.
Thank you in advance!
