Babysitter Needed for my Children

We are looking for a great nanny for 2 children in Houston. We would prefer someone who could help out with light housekeeping and homework help. We would prefer a nanny who has their own car, who is comfortable with 1 pet a mini chihuahua who stays to her self but can be greedy when eating. Occasionally barks at the unknown but harmless, and who is CPR certified. My 10-year-old may need help with homework and may need help with pick ups from after school activities. Hours right now are currently veries, but will inform ahead of time. I also work from home and will be home just can not be too attentive.
