It's tough. Frankly, I would recommend new teachers begin as a community tutor, even if they're fully qualified to be a professional teacher. It would allow you to take some time to build up feedback and good lesson numbers, and incrementally raise your prices as you develop a following of students.
Italki then allows you to switch to professional teacher, if you have the qualifications. You might consider asking Italki if you can "switch back" to being a community tutor, although I'm not sure if they will do so.
Edit: You might be able to offer a low price on trial lessons? It's something, at least.
