Sitter Job in Seattle, Washington

I have a five year old son that I need a babysitter for available from 8am to 11pm, for work shifts that could fall each week between those times. I only need these two days right now and, as I work retail, a good portion of hours' work can be expected on these days. My son is really fun and loves to play and learn. I am located in North Seattle and would need someone who can pick him up from school on Fridays (and maybe dropping him off to school that morning, though that is unlikely) and have that open availability for shifts on Saturdays. Please contact me to discuss further details.
