HI Mike, There are two categories of teacher. A tutor who just needs to be a native or fluent speaker but is limited to the amount that they can earn; and a professional teacher who has a qualification granted from a university that says they can teach. If you'd like to register with italki as a tutor or teacher, you need to have a full profile, complete an application form, and send them copies of your certificates, CV etc. Go to the bottom of the page and you'll see a link that says "Become a teacher on italki".
