Part time Personal assistant needed in Santa Monica

We have a wonderful young family that needs a personal assistant 2 days a week for 6-7 hours a day. The family consists of two babies (19 months and 4 ). There are no childcare duties but you must be family friendly. The duties include errands, vendor managing, research for travel, and any other assistant duties needed to keep the house running. There are no animals, and the job is very straight forward.
