Help #Chicago Supplier

Hello, I am an Artist currently out of Matteson, IL and looking for a nearby source for clear and colored cast acrylic sheets that will require to be cut down to size to fit into my laser cutter. When would a good time to come by and speak to some one for my needs and get some advice/materials when it would comes to gluing acrylic together? Thanks for your time and hope you are looking forward to the Fall Festival this weekend. -Mark
