Looking for a full-time nanny in Pelham, NY for two boys

Looking for a full-time nanny in Pelham, NY, within walking distance from MetroNorth. I am a single dad of children with disabilities - two boys aged 7 and 10, who have autism and are non-verbal. I need help mainly from Monday to Friday, starting from:

• 6:15 - 7:45 - waking the children, feeding them, and taking them to the bus.
• 2:30 - 9:00 - picking the children up from the bus and caring for them until the evening.
  Most days, once or twice a week, I will need a longer shift as I work late.
  Minimum 40 hours per week. I prefer someone who can drive and will help keep the house tidy. No smokers, please. Salary to be discussed. Please contact me by phone.
