Reliable Sitter Needed - monthly Saturday evenings

Looking for a calm, reliable sitter for my 7-year-old for a standing monthly Saturday evening (approx. 7-11 PM). The evening will be low-key - she'll be fed and bedtime routine will be in progress or nearly complete. I am looking for someone comfortable with helping her settle in and then supervising while she sleeps. Must be comfortable with cats as we have one in the home. Located on the west side of Jacksonville. Potential for additional jobs on weekday evenings and/or Saturday afternoons if interested.
