looking for teachers

Hi I am a Social Sciences teacher in New Zealand looking for a teacher with a class overseas to correspond with my students. I have a regular year 9 class, and an alternative programmes class who are year 10 but have an average reading age of year 7.
We have corresponded with a Ugandan school in the past, and plan to work with a teacher in Wales this year, but would like as many, and as broad a range of options as possible.
Any help would be appreciatted!
