Do you need to practice English conversation?

Hello! I am a young Argentinian woman and I speak fluent Spanish, English and intermediate level of French. I want to offer lessons to people with an intermediate level of English, who would like to have a conversation class to practice their English skills.
How did I learned English? I studied it by my own when during my early teenager years, and when I was 16 I spent 9 months living in the United States, as part of a cultural exchange program, which helped me to gain proficiency in the language.
How would a class with me be? I am not so into grammar, I believe that languages are learned by practicing and making lots of mistakes until you get better. I did not study English following grammar structures, so If you are interested in learning like me, speaking about any topic and receiving feedback and corrections, you are very welcome to try!
