Temp Nanny needed for teenager in Santa Monica

We have a 15 year old boy staying with his grandmother this summer. He will be in Santa Monica but his camp will be in the valley off Coldwater Canyon. The grandmother needs a big sister type who can pick up the boy, drive him to his camp and bring him back to Santa monica in the evening after camp. You will be needed June 15th – July 5th . Rate is $40 per hour and the grandmother will reimburse for gas in your car.
Westside candidate preferred. The dates of the temp position are June 15th – July 5th so please be available for every day! Because this is a temp position, we will only be able to place someone that we have worked with and placed in the past. Thank you
