Babysitter Needed for my Children

We are looking for a great nanny for 3 children in San Antonio. We would prefer someone who could help out with dropping off son to school watching my to younger girls while I work from home and then picking up my son and homework help until my sister in law or husband get home. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified.
