Links of online English teaching companies (and how they’re paid through Paypal)

Does anyone here have any good links of Online English teaching schools?

Usually these companies are small, and operated by a few people.  There is a pool of teachers (their physical location is not important as everything is virtual), and students communicate via webcam, and teachers are paid using a combination of skype/paypal.

TalktoCanada dot com is an example.

I am looking to supplement my English teaching income in my spare time.  I have all the equipment.  All I need is the contact email addresses of these schools (the more, the better).  Once I have a bunch, I can start contacting them with my CV, and fill up my schedule with online classes.

I believe the going rate is 30cents/min, but I could be wrong.  Also, there’s paypal fees to consider (depending on currency conversion, and what country your bank account is listed under).  Using skype implies a fee as well, though the schools seem keen on paying teachers with credit card through skype. 

Anyways, if you have links or have worked with these kinds of companies, and would like to help me, I’d appreciate it.

Thank you
