Babysitter Needed - Now Hiring

I am looking for someone to help with after school logistics for 2 children in Miami. I would prefer someone who could help out with light housekeeping and homework help if necessary. I need someone who has their own car and who does not smoke. The kids go to different schools and have activities that require transportation. The exact times and start date are negotiable. Kids get out of school at 3 and I need someone to be an extra hand to help me get them to activities, eat, and other logistics.
