Nanny Job in Calgary, Alberta

We are looking for part-time casual help in Tuscany near the LRT. I am currently on maternity leave and will be going back to work in December. We have a 10 year old daughter and a 10 month old son as well as 2 small hypo-allergenic dogs that like to bark. We are not currently looking for full-time help but would like to have a list of baby-sitters that we can trust and call on when we need a day away or a few hours to get some rest or errands done. There is a possibility for full-time live-out in December when I go back to work if we find someone that fits well with our family. Non-smoking household as we have allergies. Would like a Police Clearance, First Aid Training, and experience with babies as well as pre-teens. Thank you!
