Greetings Jeff:
Based on the geographic information you provided, I would contact http://www.lumberjax.com/index.html or look for firewood distributors in your local newspaper. Unfortunately, I am not aware of a Firewood Distributor list available from the state of Illinois.
Sorry this took so long, but I needed to determine if there were any firewood transport regulations you needed to be aware of due to the Emerald Ash Borer Quarantine for north Cook County.
Hope this helped!
