Do you advertise on this site? If not, go to the Members section and place your ad. I also advertise with Godaycare.com and I ask friends who work for large companies, the hospital, university, etc. to place my ads. These types of places have internal systems and you can reach so many people that way. Make sure you ask family and friends to spread the word and be on the lookout for you for their friends and family who are looking for daycare. I have had the best clients sent to me by referrals from friends or even past clients.
This is the best advice people gave me when I started. Make yourself a website, mine is with freewebs.com and it never costs anything. But there is a contact page so that once parents read my website they can contact me directly without leaving my website. Put your website link in big, coloured letters on all your ads.
