Looking for someone to help me learn English

Hi, I'm from Brazil, so obviously I'm a native Portuguese speaker. I really want to learn English; I already know the basics and a little more. I can read a lot of stuff in English and watch some things entirely in English. But when it comes to speaking and forming sentences, I just freeze up, and I also have trouble with pronunciation. I’m a pretty talkative person, so I could be a great language partner if you want to learn Portuguese or just talk. I like to speak about all different things—for example, literature, movies and TV shows, music, studying, and just talking about life. Anyway, I’m looking for someone to help me with English, too.
