Babysitter - Now Hiring

Hi - I need coverage for 2 kids (ages 7 and 11) starting at 9:30 a.m. on Monday 7/20. End time is a bit up in the air (could be as short as 1-2 hours, or possibly most of the day). Sitter will need to transport kids to swim lessons at Harvard town pond (10 min from my place, 10 - 10:30 am). I'll pay minimum 3 hours even though it's possible I'm done with my appointment earlier.
