I would say at very least, minimum wage. Personally, I wouldn't do it for less than $15/hr. It may seem steep, but if you want a professional provider, this is reasonable. Yes, before and after school care in a home daycare or facility is cheaper, because the providers are able to bring in more children, thereby making enough money to make it worthwhile. Of course, this is just my perspective. Others may feel differently.

I think you would likely want to know about her experience, particularly with this age group. What kind of activities would she be doing with your daughter? Television time? What happens if your child or the provider is ill? I've been out of the in-home care business for a long, long time, but these are things I would expect to be asked.
