How much the set up cost would be for a school for a english teaching for koreans?

Answer 1

There wouldnt have to be any cost at all. Cost only makes things easier. You could start out by teaching out of your home. Design, print, and distribute your own flyers. Make your own teaching aids.

Of course all of those would be easier if you put some money into it but how much would be everything from $0 to thousands.
