I'm a native English speaker (American English) and I reside in New York City. I taught abroad a few years ago, and did get my TESOL certificate. I need to make some extra money, so I was hoping to offer some English Conversation classes via Skype and charge $20/hour, or so. Has anyone done this? If so, how did it go? I guess the toughest part is getting students. I have no idea how to do this. I put in an ad in craigslist (Tokyo), but that's about it. Any ideas? or should I give up? I need to make some extra money and was hoping this would work...please advise.
