Teaching German via Skype

Hi, I am looking for a native German speaker with good knowledge of English language. The project is to teach German - reading, speaking and writing - over skype, to a thirteen year old child . The child speaks English fluently and would like to learn German. Since this likely to be a multi-year project, I'd like to have someone with interest in teaching. My initial thoughts are that 2 lessons per week might be just right with each lesson of around 45 minutes. Thanks. VickM
