Babysitter

I am looking for a great nanny for my son in Portland for when I travel for work. I would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets, who is CPR certified and who has college degree, however open to providing a vehicle as well as housing (home has separate living area for care taker). Job could be just when I travel or could be a more permanent live in arrangement with help assisting with the child as well as helping to manage the household, run errands, etc!
