Pet Sitter - Full-time / Part-time

My boyfriend and I have an almost 2-year-old Shih-Poo and we realize that everytime we have company, whether it's family and friends staying over (which is rare) or a cleaner come by, she barks non stop. We've been living in NC for almost 2 years and don't have any family or friends here that can come over frequently so we can desensitize her to having people in our home. I want to hire someone to come over a couple of days a week for only about 30 - 60 mins to just get her used to someone else randomly being here.
