Looking for a Tennis Hitting Partner for my daughter

I'm in search for a (preferably) female college/high school student looking for a little income to hit tennis balls with my 9 year old daughter. She's not your typical 9 year old, so I would like the player to be in the 4.5 + range. This wouldn't be teaching, just hitting, likely for an hour here and there over the summer. It would likely be in the afternoons. Weekends, we are more flexible.

Must be willing to play in Menlo Park or neighboring cities.

Let me know if anyone is available or someone you might know of.

Thanks!
