If you want to learn Portuguese seriously, I can help you with classes, tutoring, and didactical material. If you want to talk only, I am just one person among many ones. Notwithstanding, you can always choose what you want in classes, and I will do the best I can for it. I realized that foreigners learn Portuguese very incorrectly because people do not want to explain certain things that are more complicated. However, when you overcome this barrier, you will impress everybody.
