Childcare Needed

I'm looking for a reliable, caring babysitter/nanny to help with my two young children. I have a 3-year-old and a 4-year-old. Our 4-year-old is on the autism spectrum so experience with children with special needs is preferred but not required. Immediate need: I'm looking for someone who is available this Saturday through Tuesday, for approximately 4 hours each day. Ideally, these would be afternoon hours, around 1:00-5:00 PM, but can be flexible. Ongoing opportunity: If it's a good fit, I'd love to find someone who can continue helping 3 days per week, ideally Monday, Wednesday, Friday from approximately 1:00-5:00 p.m. The schedule can be discussed and may have some flexibility.
