Family of 3 with a dog

A couple and a 5 year old boy and our dog is 10 year old. Our common language is English at home. Me and my husband are also working full time and we are looking for a helper to help to take care of our family. The main duty is taking care of our son. Taking care of his meals, pick him up from school, going out with him to play or activities and tutoring him of the simple homework. Also, we want our helper can walk our dog once a day. For the rest of tasks are mostly normal housework and cooking dinner. It would be nice if our helper already knows how to cook the Chinese and simple western food, however, it’s not a problem if she doesn’t know very well but she is willing to learn.
