any native Mandarin speakers

Hi,

I am not going to  Mandarin classes but am trying to learn Mandarin (I signed up for a series of classes, but they were cancelled). I have got materials and I am going to  Mandarin meetups, but would like some for  one to one speaking practise. I have done a bit of teaching english as a foreign language in the past so should be able to help someone who needs an English teacher. A language exhange would be much appreciated, I have skype and webcam so it will be easy to communicate.
