Go to the home page of italki and apply to be a teacher. You have to answer some questions and pass a language test. Then wait if they accept you or not. I was a professional teacher in The Netherlands, so they accepted me quickly. Are you a teacher? If not you can apply to be a Community Teacher. You can have conversations with people in your native language then. Good luck with applying! Once you are a teacher, you can set your own dates, times and prices.
