Nanny Needed For My Children

We are looking for a great nanny for 1 child in Houston. We would prefer a nanny who has their own car, who does not smoke, who is CPR certified and who has college degree. I am seeking care for two hours in the early morning so I can go work out, my son will likely be asleep till 8 a.m. so there wouldn't be much care needed. I really just need someone to stay with him while I am gone. Preferably somebody who lives in the 77007 area or nearby.
