School run /occasional evening babysitting

Morning school run help needed. We are a busy family living in Glen of the Downs with teenage children aged 11, 13 and 15 in school in Dublin and Enniskerry. We are looking for a morning school run help from ideally from 7.30- 9.30 am but would also consider someone who is commuting from greystones area up to dublin everyday who can drop my son to school in Rathfarnham for 8.15am. Help on Saturdays would be a bonus and also evening babysitting on occasion. Must have a full clean driving record, be diligent and reliable. Use of a family car may be possible. To start in early September
