Pet Walker - Full-time / Part-time

I am looking for a part time family assistant with an emphasis on pet sitting. I have three small dogs, four cats and a tortoise. Ideally, I am looking for a person that can visit my dogs and let then in the backyard for supervised play. Clean/Scoop/Refresh the Cat boxes, vacuum floors, provide cat treats; and feed the tortoise and check his pond and heat lamp. In addition to pet sitting duties, I need an assistant to run errands such as drop off and pick up of dry cleaning; lite grocery shopping; package retrieval, etc.
