Detailed oriented house keeper

I am looking for someone to help clean my townhouse every 3 weeks. It is a 2000 sq foot townhouse, however I only need certain rooms cleaned. I am a resident at UVA hospital working 80 hours per week and I just don't have the time to clean like I should and I own the condo and want to keep it nice. Two other residents rent from me, so there rooms would not need to be cleaned. In total, I would need the living room, dining room, downstairs bathroom, kitchen, master bedroom and bathroom, and the upstairs bathroom and bonus room cleaned.
