LA Ladies ... afterschool nanny?

[formerlyak]

Hey ladies. Do any of you here in LA (or other similar metro area) have an afterschool nanny/babysitter for your child? Mine is in first grade and currently goes to the afterschool program at his elementary school, but as he gets older and more involved with things like sports, I was thinking an afterschool sitter/nanny might be the way to go. This person would have to be able to drive ds to soccer practice and the like and help with homework. I had some friends in college who did this as a job all through school and loved it, so I am thinking a college student would be ideal. I'd need 10-15 hours a week.

What is the going rate for something like that? If you have a sitter like this, how did you go about finding him/her?
