Maternity Leave Help -3-4 Hours A Week

I am looking for someone to come once a week (flexible on when during the week based on your schedule) for 3-4 hours to watch my newborn daughter so I can either nap, get some stuff done around the house, or get out of the house. My husband does work from home and will be around as well. We do have a friendly hyper dog. This would go on until May. After May, we would love this person to be our sitter for date nights as needed but it would not be 3-4 hours a week guarantee after that. Must have experience with newborns and infants.
