Advice for English Language Teacher

Hi all!
I am a native English speaker from Ireland. I will be moving to Vietnam in August for (hopefully) 2-3 years to teach English. I have a 3 years teaching experience in a number of subjects, honours bachelor's degree in Applied Sociology and a TEFL certificate.  I would really like to hear from others about their experience of teaching in vietnam-how many hours can i expect to find? the average pay? Do you work more than one teaching job and really any other advice you can give me before i travell.
Kind regards,
