hi kaew072, you can try Lao Dong Club in Ho Chi Minh. Look for Thuy or Thao(lady) or Loy where they are all coaches. The best time to look for them is between 10am-3pm btw, if you are down here(Malaysia), you can look for me, Jason and contact me at 012-3221148. If any of your friends are down here looking for a coach, I can recommend them a good one. Jason.
