Looking for a house/dog sitter for elderly dog in March

I'm looking for someone (preferably a grad student or older) to housesit and care for my 17-yr-old dog from March 22-27. She can be left alone for 8-10 hours during the day, but needs someone to stay with her at night. I live in Sunnyvale, within walking distance of the CalTrain, the Sunnyvale Farmer's Market and Murphy Ave, which has lots of restaurants, a movie theater, Target, and Whole Foods. Pay $300.
