You should be CPR certified. You may be able to charge a little more than other home daycares if you can offer more than they can. This information is for sale for a small charge. Remember to ask the daycares you call what they provide and again, you may be able to charge a little bit more for providing extras. A hot nutritious lunch is a nice touch, and parents won't have to bother fixing a lunch for their child every day.
Advertising is straightforward, but expensive.
There may be different papers to advertise in so compare the prices. I was lucky enough to get responses almost right away, but be patient. Reading other people's ads helped me to get a feel for what to say in my ad. Remember to think about what would draw your attention to a home daycare ad. Also remember to include anything you are doing to make your daycare special and unique.
