Babysitter

We are looking for a great babysitter for 1 child in Denver. We would prefer a babysitter who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified. She is 11 years old and non verbal and in Wheelchair and diapers. My needs are every Monday and Tuesday evenings and a couple of dates on Friday or Saturday evening and occasional all day Saturday ( perhaps once a month). I know these dates months in advance
