Sitter Job in Cleona, Pennsylvania

I am a single parent of two children, ages 7 and 8, with a job that requires me to work from 6:30 am till 3:30 pm. My commute is about 20 to 30 minutes. I am looking for a person who can either watch my children at their home or at my home from 5:45 am till their bus picks them up for school in the morning. I am not certain on the time it arrives yet but it seems like it is around 8:00-8:30 am. I may also need another sitter to watch them from around 3:15 till 4:00 pm. I am not sure how much to pay someone for this service so please let me know what you expect to receive. This would be a long term situation that once accepted I would rely on Monday though Friday till the end of the school year so please be serious if interested.
