Recurring Sitter Needed For My Child

My son is very active, is starting to cruise the furniture and walk with the aid of a toy walker or peoples hands. During the day on the weekends we enjoy going out for walks, he loves being outside and is quite happy going on a 2 mile walk. Im looking for a regular sitter who is available for some daytime Saturdays and evenings on either Friday or Saturday. Im a single mother so having someone who can do either the daytime or nighttime hours would be a huge help. He usually goes down for bed between 7-8. We are working on decreasing nighttime feeds and have gotten down to about 2 (around midnight & 2-3 am).
