Dear Taehee, I am part of a English training institute in India called English Channel. We train people on spoken English, but we deliver our trainings on phone/ internet using skype to learners who can be anywhere from teachers who can be anywhere. We currently offer this service in France- we are keen to extend this to Korea. will you like to partner with me on this. This provides the learners a flexibility of times without having to go to a class room. They are assigned a teacher and they interact as per pre-defined schedule.
