Seeking information

I haven't had any response so perhaps I'll change tack. 

Seeing as It would be an unpaid internship, I'd need some money to cover expenses.  I'd like to be able to support myself in at least shared apartment (but ideally living on my own), including internet access.  I have a professional post-graduate degree, but no English teaching certification or experience.  In the experience of forum members here, would teaching English a few hours after work and on the weekends be a viable way to generate cash for living expenses? Can I expect somewhat higher earnings as a private tutor for "Business" or "Professional" English? Should I be looking at Freelancing as a tutor or looking for Part time teaching opportunities with established companies?

Are there any bank account restrictions or laws against bank transfers out of Cambodia?

Any other issues anyone thinks I should take into account?
