Babysitter - Full-time / Part-time

We are looking for a great babysitter for 1 child in Houston. We would prefer someone who could help out with homework help. We would prefer a babysitter who has their own car, who does not smoke, who is comfortable with pets and who has college degree. I need someone to keep an eye out in the evenings, help with homework and make sure they are safe while I travel for business.
