Nanny Needed

We are looking for a great night nanny for 1 child in Pittsburgh. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets. We have one 25 pound dog. The night nanny duties would be for two months from early June to August. The night nanny duties could transition to daytime nanny duties starting in August as my wife and I both return to work full time at that point and will need help during the weekdays. Thanks, Ryan
