Casual evening baby sitter

I'm after a baby sitter / mother's helper from late July to mid Sept. 4 days a week (weekdays) from 5-8pm (negotiable) for our evening routine as my husband works late. I have a 9 month old and a 5 year old. I am looking for assistance to care for the 9 month old while i cook, feed and get the kids ready for bed. Please let me know if you are available and your asking rate.
