Tutoring who or what?
The answers would influence what kind of preparation you might do. I hired a tutor for my unschooled 16 YO DD, because she and I don't stay as structured as she wanted for certain subjects. The tutor tested her (in the subjects we requested), and came back the next week with a formal lesson plan/syllabus drawn up. I think most of the tests and worksheets she uses come off the internet. We are very happy with the progress she is making. She charges $20/hr, which seems to be about the going rate here, and seems fair to me. To tutor schoolage kids, you might be able to put up flyers at libraries, schools, rec centers, etc.
I have an ESL teaching certificate, and advertise on Craigslist to tutor adults in English. I plan to post a flyer at a couple local universities that have exchange student programs. I am brand new to this, and have temporarily put it on hold, due to family emergencies, but hope to get back into it in the coming weeks.
I have come across several websites that accept free ads from tutors in my area.You would want ones with local presence in your area, but a google search should turn up some avenues.
I might have more specific suggestions if I knew more about what you are planning to teach. I would also love to hear from others to share experiences in this field.
