Help with Monday-Thursday Childcare School Pick-up

I am in need of a responsible individual to help with afternoon school pick-ups (and potentially morning drop-offs). My wife works from home and we have a live-in nanny (who doesn't drive). Compensation will be very competitive; depending on the individual, willing to make this a salaried position (time spent at the task is not all that relevant; dependable execution of the task is what is valued). Children are 3.5 and 7.5 years old. Driving distance between home and school is 4.7 miles and takes about 13 minutes (essentially from A1A / Corona to Canal Blvd / Roscoe Blvd in Ponte Vedra Beach) . Pick-up time is around 4pm each day. Drop-offs are from 8:00-8:30am. Our live-in nanny could provide pick-up and drop-off assistance, if required. Job requires a car and room for 2 car seats.
