Lessons French

Help, please. Our new au pair has arrived and wants to take beginners lessons in French. All usual language schools are full (CPAB, EPFC, VUB). We live in Brussels. Does someone know of a language school that does lessons in the morning, 8h - 12h per week, 4 levels a year, and that does not cost more than EUR 400 per level? - And that is not fully booked? If the aupair is not enrolled in language classes he cannot register in the commune.
