It is also great for current teachers who are looking for more hours.
Golden Voice English (GVEOE) is based in Toronto, Canada and teaches English to students in China in grades 1 to 9.
They offer a wide variety of curriculum and they do both group and 1 to 1 classes. Voxy is based in New York, they want native speakers with a degree or TESL certificate. Click here for the comments and the Voxy review page. They coach adults in the tech industry on language & communication skills.
I have had interviews with several of the companies on this list and I am currently working for one of them. They mostly teach business English, but most of them offer test preparation, group and individual classes too.
This is a list that I will be updating, please leave a comment if you have any experiences with these companies or know of any others that should be added to the list.
Personally, I teach English face-to-face in the morning and online with Skype in the afternoon.
