Hi M.!
I am currently listed on enannysource.com and think that would be a great place for you to go and search for what you need. You can set up a family profile, what you need, times ect. and other prospecting Nannies can search your profile and you can search theres as well and get in contact with the ones that catch your eye. I am listed as a Nanny, so please contact me if you feel I fit what you are looking for. When you sign up you get a 30 day free trial, and that should be more than enough time for you to find what/who you are looking for.
Hope it works out for you!
A.
