Walker Needed For 3 Dogs In La Jolla

We need a walker to walk 3 dogs in La Jolla. Two dogs walked together for one hour and one dog walked separately for one hour. Twice a week, days are flexible. We live on a busy hilly street so you would have to drive to a near by flat area to walk. My days are flexible. My dogs are Golden Retrievers. They are trained therapy dogs. I would like this to be ongoing . Ideally I'd like the walk to begin at 9 a.m. until 10, and the second walk from 10 a.m. until 11.
