Senior Caregiver - Full-time / Part-time

We need hands-on care to take care of my father in Knoxville while I am on vacation from 6/27 - 7/4. We need someone to come for 2 hours in the evening to make sure he makes it into the bed safe. He is in a wheelchair but can take a couple of steps with help. Preferences for a caregiver who is a non-smoker.
