CNC foam part supplier- Chicago

Does anyone have a Chicago area supplier that can take a 3D CAD file and CNC out a foam part for a resonable price. Could be a small shop or garage operation. 3-axis is all that is needed.

I’m trying to get a full scale mockup of a part that’s about 3 feet by 2 feet by 1 inch thick. Other suggestions also welcome.
