Part time (afternoons) nanny required for 3 girls.

I have 3 girls aged 5, 7 and 10. I would love someone to collect from school and mind in our house. Ideally the minder would assist with homework and drop/collect from activities. Fluent English required with experience in minding kids. The person would also need to be ok around pets - We have a small, very calm, friendly dog. A drivers license and own car is preferable but not required, everything is within walking distance from our house.
