Want to practice Japanese (São Paulo)

Hi, everyone...I am French actually and have been living in SP for 20 years now. I am looking for Japanese people to improve my knowledge of the language (learning for 4 years already) since it is quite dificult to find someone who is fluent in Japanese here in SP. I would even be willing to trade for Portuguese lessons or any other languages (French, English, Spanish mainly) that you'd be interested in.
どうもありがとうございます。。。でわ、またね
