Who can help me find such a person?

Our Chinese learn English from a very little child. In order to get high scores or pass so many English exams, lots of us takes training course besides normal education in China.
There is few schools focus on English training in my home town, which is not very rich and has about 2,000 students. What I plan to do is that founding an English training school for the teenage students. The students in our town have no chances speak to speakers whose native language is English. So, I would like to use the internet, just like video conference, let our students can talk with the native speaker via internet. Anyone who like to speak with our little learner is OK. So, who can tell me how can I find such a person?
