Regular Babysitter Needed For 2 Children In Potomac..

I am looking for a great babysitter for 2 children in Potomac. I need someone who has their own car because I will need daily drop offs for school. Its also important to me that the babysitter does not smoke because me and my kids have asthma. It would also be good if the babysitter is comfortable with dogs because we have 2, but no dog care would be required. The job is to be here when I leave for work, get the kids ready for school (maybe packing simple lunches if I run out of time), cleaning any messes you make and having the kids clean up after themselves, and dropping them off at 9 a.m. M-F. There may be an option for additional hours on day the kids have off, if desired, but not required. Thank you!!
