There is also a wonderful market for human beings. It's called 'human trafficing'. It's interesting to re-read that article inserting 'human' for puppy or dog.
I am not implying that dogs should be treated as humanely as a person, wait....I guess I am.
There is a huge difference between paying adoption fees for a child to an adoption agency who isn't doing it 'for profit' vs. buying a child in the sex slave trade.
If this guy is sooooo intent on making a profit, he ought to sell living things that don't have a soul, like maybe human clones of himself.
