Part Time / As-Needed Weekday Afternoon Sitter Needed

I'm looking for an *as needed* sitter for afternoons to evening (5-7pm) that would be able to pick my 2-year-old and 4-year-old up from daycare at 3 p.m. You would simply hang out with them until either I or my husband get home off of work. I do not expect any housekeeping. Some weeks we wouldn't need pick up so this would require flexibility in your availability. Sometimes I am able to get home sooner than anticipated due to customers needing to reschedule appointments, but I would do my very best to communicate this to you as much in advance as possible. This would more than likely range between 1-3 times in a week between Monday to Thursday. I need someone who is flexible, trustworthy, and caring. My kids are my world, and I want to ensure they are in good hands.
