Would you hire a college kid to work on your house?

Last week my doorbell rang and it was this 20-something kid that said he was working his way through college and was doing exterior painting to earn money. My first question to him was, "Are you insured?" to which he replied, "Yeah, sure." I asked for more information about him and he handed me a piece of paper saying that he represented Collegiate Entrepreneurs, Inc. Something just made me wary of him, although he looked clean-cut and sincere. I've had bad enough luck with licensed contractors. Any opinions on this?
