If you live in Illinois, look at FFE (Frozen Food Express) which is owned by KLLM.
FFE will send you to school in Chicago at Prairie State College. The big benefit to this is you will graduate with an Illinois CDL which means you don't have to go through the aggravation of switching your new cdl to an Illinois cdl. If you get the cdl in another state, they make you do everything over again at the Illinois DMV and love to flunk people on the "Pre-trip Inspection."
