Sitter Job in Atlanta, Georgia

We are in need of a flexible/part-time caretaker who would be available for some morning drop offs or evening pick ups and then onto afterschool activities. My wife travels often with her job and my job has variable hours that are not set. An example of need would be to have someone be by in the morning to supervise kids getting ready and then take on to school. Afterschool pickup may or may not be necessary. Another scenario would be to pick up kids around 3 pm and get them to afterschool activities or stay with them until 9:30 PM with light dinner preparation. The kids are a 7 year old boy and a 10 year old girl and both are well behaved. (Non-smoker)
