[Highland Park] House Sitter?

I have a small dog and cat and live in HP.  Am trying to find a house sitter that could stay at my home and take care of my "kids" when I am on vacation.  Obviously I would want someone reliable and professional and they would have to sleep at the house -- perhaps a grad student? I am going to be away for a week at the end of Jan./beginning of Feb. Any suggestions?  Many Thanks! Margaret O'Connell Farragut St.
