Looking for an new teaching job in Chicago

I worked last year at Englewood High School on Chicago's South Side. Since the school was closing, I knew that it would be a 1 year "gig." So again I look for work. I have had several interviews but no offers have been made. My age works against me. A big milestone was the passing of an endorsement exam for chemistry. Hardest test I have taken in 30 years! I passed with a good score. If I could work in teaching computers I would be even happier. Right now I am studying the Visual Basic 2008 .Net language.
