Babysitter Needed for my Children

We're looking for a great babysitter to help watch our 3 kids - ages 10, 9 and 6. We live in Prosper near Preston and First streets. The job includes picking them up from school on Tuesdays, Wednesdays and every other Friday. School gets out at 3:10 p.m. Some days they have activities that I need you to take them to. You'll watch them at the house until 7:30 p.m. We would prefer someone who could also help out with light housekeeping and homework help. We would prefer a babysitter who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified.
