Nanny Needed For 2 Children In Winter Springs/Oviedo

I am looking for a part time sitter for my 4-year-old son and 1-year-old son in Winter Springs. I need a responsible adult with a reliable car who can pick up my boys from school around 5 pm, bring them home safely, and care for them until I get home at 7:30 p.m. The days needed are Monday, Tuesday, and Friday one week and the next week Wednesday and Thursday. Then Monday, Tuesday, Friday, etc .. I would prefer someone who does not smoke, who is comfortable with our 2 small dogs, and who is CPR certified.
