Looking for a nanny/babysitter

Hi everyone. I am in need of a nanny/babysitter that will help look after my twin 7 year old kids (boy and girl). The role would be for pick up from school Mondays to Thursdays 330pm. After school pick up, they'll need assistance with their assignment or homework, organising their foods, ensuring they have their evening showers and take them to tutoring on one of the days and basketball on the other day. The nitty gritty of what you will need to do will be discussed and agreed upon. I am a single father and easygoing. Preference is to find someone that is patient, dutiful and respectful.
