Part-time childminder required in Dublin 6

I have three children, one girl aged 7 and two boys aged 4 and 2, and am seeking a childminder who can drive (use of my car is available) to collect the children from school and entertain them in the afternoons, bring them to their after school activities and someitmes help with bedtime. Both my wife and I work full time and we currently have a nanny who minds our two year old in the day time. I am looking for someone who is energetic and fun, likes to play sports, games and imaginary play, do arts and crafts and someone who can stimulate the children's interests. We live in Dublin 6, very close to the green LUAS line.
