Childcare Needed - Now Hiring

I am a single dad that just moved to Nashville. I am a doctor at the children's hospital and unfortunately have an overnight shift this week (Sept 10) that I haven't been able to move. I am looking for someone to care for my almost 5-year-old son overnight while I am at work. I know this is last minute but my usual childcare fell through. I would need someone from about 3 p.m. through the next morning when I get off and would likely be home around 9 a.m. My son is very easy to get along with and usually is asleep by 8 p.m. I have a guest bedroom right next to his that you'd be able to stay in. Please let me know if you have any questions or would be interested, Thank you.
