Childcare Needed

We are looking for a great nanny for 2 children at our home 2 days a week for around 6 hours a day. Flexible on days if Monday/Friday doesn't work. I work from home 95% of the time so I'llbe around most of the time. We would prefer a nanny who has their own car and who does not smoke. We do have 2 dogs but they are usually kept up during the day.
