Childcare Needed

I'm looking for back-up care for my toddler next week when his regular care is unavailable last minute. Would love care starting around 10 a.m. (after I drop older kids at camp) through getting him settled down for a nap (about 1pm). Beyond next week, would love someone who may be available to provide weekday back-up care in the future and/or interested in occasional babysitting jobs for all three of our kids (aged 9, 6, and 2).
