Spanish Speaking Summer Nanny Needed For 2 Children

We are looking for a great babysitter for 2 children. We would prefer someone who speaks Spanish. Our children attend a Spanish immersion school, and we would like to continue their exposure to Spanish during the summer. The job would actually start towards the end of May as school ends and would continue through mid-August. It will be for three days a week from 8-5, the actual days could be negotiated. We would prefer a babysitter who has their own car, who does not smoke and who is comfortable with pets.
