Looking For Overnight Nanny For Second Baby Boy Due March 9

We are looking for a night nanny to help 3-4 nights a week once our second baby boy who is due in early March. We'd like the nanny to be here overnight (around 9pm-7am) for 3-4 night a week for about 12-16 weeks to help with just the newborn (ie no need to help with our older child). We are flexible on the details including how many nights a week, the time frame each night, and the duration. We have a small dog, so if you are okay with dogs, that would be helpful. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified.
