Nanny Job in Calgary, Alberta

I am looking for a part-time nanny to help us with our two girls, ages 2.5 and 4. I want this person to be interested to stay with our family longer term. I expect the applicant to be energetic, hard working and to love being with children. I am looking for someone to help me around the house, stay with the girls at home or at an activity while I am with the other one and to help clean up around the house. I can be flexible on the days of the week and the hours per day depending on the nanny's schedule. I am looking for a nanny 2 - 3 days per week or the nanny could work less hours each day and come more days if that worked better for both of us.
