more info I found on Reddit. I have no affiliation with these businesses just sharing what I found when planning my upcoming trip………

….Next up is Taxi4YouCambodia, a taxi service that you can find on FB or you can call +855 933 899 52. Prices start at $12.50 and it runs 24 hours. It will take you door to door to wherever you're staying.

Then there's Go Green Airport. They use electric and hybrid cars for $27 for the carload of up to 4 people and their luggage. Best to book the day before you arrive. Call, text, Telegram, or WhatsApp +855 86 931 570 or email [email protected]……
