There is a real market for that kind of sick stuff in Cambodia. You can organise it from several big clubs in Pnomh Penh. Armed guards will drive you in a minivan to a suitable hotel/accomodation.
Locals can buy a kid from a poor family to be freely used as slaves in rich households, the going price was 50-60 Dollars for local politicians, businessmen in 2003, I am not "up to date" with the prices now..
The (chinese) chef de bar of the then-biggest club in Pnomh Penh estimated that 70% of the prostitutes there have are HIV-infected and a minority are working for themselves/are there from their free will.
