Need babysitter for our 20-month old

We're looking for a responsible babysitter to look after our 20-month old daughter, from a few times/year to once or twice a month depending on circumstances. We live in Redwood City, 5 miles from campus, so you would need transportation. Generally evening babysitting, starting at 6:30 or 7:30 for a few hours (and our daughter goes to sleep by 8:30 every night).

If you are available Halloween evening from around 8-11 that could be a good first time.
