Overnight Care for children?

So I have come up with an idea of possibly opening up a "night" care for the sole purpose of mother's and father's who work the third shift. There are so many people who are struggling with day care/school hour issues b/c of the 7p-7a shift at work. I live in an area where there is about 4 major hospitals and think it would do very well but wanted some personal opinions from everyone on this board. Any comments/advice would be greatly appreciated! Thanks in advance!
As a shift worker for many years who once needed this service, I have to commend you on your enterprise. Hope you are very successful at it.

That is a fantastic idea! Best of luck to you.
