I am not a professional teacher though, I have one year teaching experience about both English and Chinese(Mandarin), during which I taught free of charge for most of the times. Now, I think I need some stimulus for myself in order to be more responsible and serious upon teaching, so I started to charge some fee about my courses, it's quite low I think compared to the given fees of other teachers-- only 20 ITC/ hour for my Mandarin course and 20ITC/hour for the English course. For more information about my courses, please visit my course page.
By the way, I probably will go to Europe this year in August, so this is maybe the very last months for me to teach, I really hope I can help you with those two languages.
