I hired Mr Ho - phone 092216005 - firstname.lastname@example.org and he proved a sensible and honest guide - spoke fairly good englishand was full of good suggestion
As for anything else, NEVER PAY ANYTHING IN ADVANCE Cambodians are nice and honest people, but once they get your money, tend to get sick, have family problems and all sort of fantastic impediments -and if they are with you for any extended period, they often narrate tearful stories that justify asking for an advance - DON'T FALL FOR IT over 6 years ago
