Looking For A Dependable House Cleaner For Family Living In Chicago

It would only be cleaning my room which I try to keep as clean as possible in the time that I can but I also work 90-100 hours a week with unpredictable work schedule so my room can get more messy than I like (I'm a bit of a clean freak). It would be mainly cleaning surfaces especially my bathroom, and would also like some organizational changes (this would mainly be once a month ore very other month).
