Hi!! I am brazilian!
I am as clueless as you are, sadly.. as my search is just beginning. If you are in a big city, it might be helpful for you to seek support groups.
I live half time in Paraná and Santa Catarina. I attend to UNI at SC. Anyway, if I happen to find someone good, I will share it with you.
If I find someone really bad I will share too so you can avoid them hehe.
