I have no need for babysitters, so I can't comment too much on the idea. However, I think you could make it more general (usable for types of jobs other than babysitting) fairly easily too and then it might be more useful to a larger number of people--although I know that's not necessarily what you're going for. One minor UI nitpick: the hover effect on the navigation links is very difficult to see on some monitors. I'd make it less subtle.
