Reliable sitter needed for early mornings

I am seeking a reliable individual to sit with my 6 year old from 6:00 AM to 8:00 AM. The days rotate, but it will be 2-3 mornings a week, and I will provide you with my schedule a month in advance. Pay is $20 a morning and is payable after each shift. Our current sitter is starting a full time internship and must resign. We have an indoor, large mixed-breed dog, but no pet care is required. I just need you to sit with my child from the time his dad leaves for work until I get home from work, no other responsibilities.
