Seeking English Culture Exchange

Next semester (Jan. - June of 2013) I'll be teaching an English culture class for 6th semester, pre-service English teachers, ages ranging from 18-22.  I'm looking for either a synchronous and/or asynchronous exchange with any English speaking country that would also be interested in learning more about Mexican culture.  It would not have to last the entire semester as there are many possible arrangements that could be made.  I am anticipating approximately 15 - 20 students in my group.

If you are interested in discussing this matter further, please contact me.
