Non-paid paying internships

Wednesday I traveled to the capital city of our lovely state and went to a job fair at a private collegiate institution. I filled out two applications. Today I called one of those places back. They called me back and said that although my experience is fitting they have a rule that they either give you a paid internship or on the other hand a non-paid internship but with college credits. Currently they cannot afford to pay someone and they'd like to offer me a non paid internship but I've graduated college so really the credits don't do alot for me. I continue to play the game insearch of my $42,000 a year job. Did you know the State Police pay $40,000? that's close enough for me...a viable possibility. Can you imagine that?
