Au Pair or Nanny Wanted in Cardross - opportunity in United Kingdom

I am a single Mum with a 9yr boy and 11yr girl. I currently work full time (4 shifts a week usually), so need help before/after school and the odd evening. We live on edge of lovely friendly village which is about 30min to Glasgow and just 15min to Loch Lomond. We have a dog and 2 cats. My Dad also lives nearby and helps.
