In our area we have Community Childcare Connection that has lists of DCFS providers.
Honestly, though, word of mouth is so much more reassuring to me. I would talk to friends and neighbors and call local churches. Ask people who they have used or who they know that is using a provider or who is a provider.
If you have school age kids or preschoolers you can call your local grade school. They very often have lists of providers for after school care, and many of those providers will also do all day care.
Good luck! It can be a scary step, but just visit places and trust your gut. It really does work.
