Babysitter Needed

We are looking for a nanny for our 2 daughters who are 11 and 13 in Saint Helena. We would prefer someone who could help out with school pickup at 3 p.m. and support driving to/from afterschool activities, some weekends and overnights as well as pet/housesitting. We would require light housekeeping. We would prefer someone who has their own car, who does not smoke, who is willing to drive children, and who is comfortable with pets.
