I want to know a good place to advertise my daycare business

http://www.KidzCareDirectory.com directory is a well-child care. They have some interesting options for the design of your list ... This makes your business look much nicer then just ad on craigslist or something. You should take a look!

Facebook might be a good source to advertise your child care among its friends in the local area. Other media in your area should do the trick!
