We're looking for a reliable babysitter for our two children, ages toddler and pre-school.

We either want:
a) Someone between 7pm (after the kids go to sleep) to 10 or 11pm. Days for this is flexible.
b) Sick day coverage when they cannot go to school. (Parent will be home working.) This will be last minute of course.

We have a friendly golden retriever dog who can be shut away in a room, but would love some attention from someone dog friendly.
