Babysitter Needed for my Children

I am looking for a babysitter for my two kids (6 and 4) during afternoons weekdays. I am looking for someone who can show up with a planned activity (I will buy supplies) as afternoon enrichment. This can be an art activity, scavenger hunt, board games, science experiment, etc. This will be inside my home while I run errands in the middle of the day. Must be a reliable, non-smoker who is comfortable with two curious little dogs as well. CPR/first aid certified is a must. Experience with autistic kids and special needs a huge plus.
