Childcare Needed - Full-time / Part-time

Hello, I am seeking someone who is able to assist with childcare as needed when my son's daycare is closed or days that I may be working longer than usual and won't be able to pick him up before his daycare closes, as I am a single mother. These would be the days I would need full day care. I have no family in the state of Arizona who can assist when needed and I am looking for someone who would be the best fit for my son and I. My son will be turning two at the end of September and is pretty easy going. We do have a 3-year-old cat named Mushu who is very social and loves to lounge around and play with my son.
