If there is a valid copyright infringement issue here, you might not have a hard time getting a lawyer to work with you "on spec." I believe the copyright infringement awards tend to be rather large (not that the offender necessarily has the money, but they can garnish wages, etc.). If you have been infringed upon, I suggest talking to a lawyer. You may find out you don't need to pay up front and you might get some satisfaction and some money out of it. Good luck. Frank
