Childcare Needed - Full-time / Part-time

We are looking to hire an occasional babysitter for a 5-year-old and (will be) 6-month-old. We have a few occasional dates needed already for the end of October to beginning of December. Mainly on Saturday/Sundays while my husband is away. The hours we need for those days would be 6:30a-7:30p at my home. However, I am okay with you taking them out to the park or events. We currently have a total of 7 dates needed for childcare. And then after December we would just use care on a as needed basis if we need to work overtime or what not! We are looking for someone reliable and with their own mode of transportation.
