If you are a complete beginner, you can add me on Skype (ma3te4), and I will teach you myself. I have recently begun teaching people, to gain experience, using my own experience of learning Chinese. I already have the structure from those people's lessons and the documents I send them (to help them remember the lessons + vocab), so helping others is little extra work for me. And best of all, I'm doing it for free. :P This applies to anyone learning Mandarin, by the way.
