Childcare Needed

We are looking for a great babysitter for 2 children in Round Hill usually on days the kids don't have school but we have to work. I would prefer a babysitter who has their own car, who does not smoke and who is comfortable with pets. Our pre-teens are largely independent but would benefit from fun activities like jumping on the trampoline, walking to the corner store, playing video games with someone, etc. An energetic person with lots of ideas would be ideal.
