Childcare Needed

We are looking for a great overnight sitter for 2 teenage girls in Grafton. I am a single parent, and often need to travel for work to New York. I need someone who has flexibility to be stay with them overnight. The days this includes often varies from week to week. Invariably will be 1-2 partial or whole weekends a month. Flat rate of $200/night. Expectation is to arrive in the evening and be here through when they wake up in the morning. They are very smart, independent children and my eldest has a license so there is minimal driving expectation. If my eldest has other activities, may ask you to drive my youngest to friends or sports practice, etc
