Nanny Job in Calgary, Alberta

I'm looking for a nanny to work part-time starting in mid-August. I need every Tuesday, Thursday and Friday. Friday's can be flexible as I only work every other Friday, so we would talk about whether you would like to nanny only on my working Fridays or if you would like to work every Friday even though I'm home for some of them. I have 3 children (2 boys ages 6 and 8, 1 girl age 2 1/2). The responsibilities would be getting my 2 school age boys on and off the school bus and then looking after my 2 1/2 year old daughter throughout the day. The hours are 7:30am - 4:30pm. We live in Wentworth/West Springs SW.
