How to Find a Night/Baby Nurse

I'm exploring the idea of having a night/baby nurse come for ~2 week since it's our first child.  We are hoping that they can help teach us the ropes and help with things like breast feeding (even though it sounds like not all of them do this).  I've already asked friends for recommendations but everyone already seems to be booked (my due date is in mid-August).  Any recommendations?  THANKS!!!
