I don’t know about the Craig’s List part. I’ve never spent any time there.
He is on LinkedIN: http://www.linkedin.com/pub/heberto-ferrer/17/995/2b6 If you click the link to his page, you see some of the same images he has on 500px, and his page says he is in LA, plus there is a phone number. His profile says he went to Santa Monica College (Associate of Arts (A.A.), Comercial Photography, 2007 – 2009) and has been doing photography for 5 years.
Apparently there are deals to be had on Craig’s list.
