Sitter Job in Lake Louise, Alberta

I am looking for a babysitter to watch our two toddlers (2,5 and 14 months old) for an evening while we are on vacation in Lake Louise. We will be staying at Paradise Lodge, and will be going out for dinner and a walk, we were hoping to get a sitter from 8 pm until 11.30 pm on Wednesday, July 27th. We will do our utmost to ensure that the children are asleep before we leave. Will need to have your own transportation. 20$ CDN per hour, references required, and would prefer someone local, so we could meet briefly the day before.
