Try www.lakecountyhomedaycare.com it is a list of licensed providers in Lake county. I myself am on the list. I live in Antioch which is probably in the wrong direction. Check it out I know there are tons of providers in your area. Phone numbers are listed for you and you don't have to pay a fee or talk to anyone to get the list, which means you can do it at your convience.
You can also try the YWCA, I know they keep a list of licensed providers.
If all else fails you can call DCFS yourself and get a list of providers. Not all providers advertise or join certain organizations so they are not all listed in one place. DCFS should have a complete list, though I don't know how long it takes to get the list.
I hope this helps!
Good Luck and let me know if you need anything else.
