House Cleaner - Full-time / Part-time

I work 40 hrs a week and take care of my elderly father who lives downstairs. His apartment would not need to be cleaned, I will take care of that. I have back and knee problems so I'm not able to keep up with my house and it's getting away from me. I have a small dog and two cats which are all friendly. The windows would only need to be done probably in the spring and fall, not a big deal. I need someone to dust, which I hate to do, vacuum, scrub floors, clean bathrooms and any crud. Would appreciate any help.
