Nannies?

I thought that awhile back ago I saw on this site a website of where to find a nanny locally. Does anyone know what I am talking about?? :-) I know I have always wanted to work with kids and my job is driving me insane! I have been going to school to become a preschool teacher and I'm thinking maybe I could get into babysitting/nanny-ing full time...I want a job where I can be busy and active and I know that would be a great opportunity! :)
