I am currently in Hanoi. Im a qualified TEFL teacher but im looking at just teaching conversational English.
I would be very grateful if anyone could give me a few pointers to get started.
Click on the jobs link in the top right-hand corner and look through and see if there's anything you want to do there. If not then look on various websites for the contact details of schools and ask if they need any teachers and offer to send your CV. Otherwise you can get on a motorbike and appear in person or just simply hang around the expat bars and ask around.
Right now is a week before Tet so things are pretty slow at the moment though should pick up by March.
If you're looking to teach conversational English, perhaps privately, see this thread http://tnhvietnam.xemzi.com/en/aska/answers/qid/8905 for some guidelines on how to promote yourself on TNH.
