Khmer language lessons

Does anyone know of a personal tutor in Penom Penh who specialises in teaching Khmer to foreigners? This would be of much help to me. At least where should i start to look for one, preferably female (i usually find they are better teachers of languages).

Many thanks to all replies.

My personal tutor is looking for some extra work. She would no doubt enjoy the respite from having to teach a dullard like me. I have sent you a personal message wirh some details.
