There are a number of expat forums that you might consider joining. There you can ask expats via the forum or private messages about their actual experiences. For many destinations: InterNations.com, expat-blog.com. For Cambodia specifically: cambodiaexpatsonline.com, khmer440.com, and a recent addition thekhmerforum.com.
I spend a good deal of time in Cambodia and love it here, although I don't live here full time. Considering you are living on 20K in Las Vegas, you might be able to do 12K in Cambodia. I would not want to do it on that little, but you are young and hey, life is not only about money, it is about experiences too. There are many expats here that have a good life on relatively little. You can also get a job here teaching English. I would plan to get the TEFL certificate if you want to that. Also could volunteer for a while at an NGO then transition to a paid position. Note, you won't make much, and you may work long hours 6 days a week. Another reason to check out the forums is that you can make contacts here before you try to relocate. Good luck whatever you decide!
