Has she checked out
www.keen.com? I'm in the adult section, and make decent money when I sign on. Just cruising around, it seems that psychic readers and some of the advice people are doing pretty well too.
eBay is a nice hobby for catch and release antique and collectible hunters, but it's really time consuming to make much money there. Worth a shot, tho. She should also check out half.com. I buy most of my books there.
www.wahm.com (Work at Home Moms) often has links to genuine work at home opportunities, telecommuting jobs and the like.
Hope this helps!
