House Cleaner - Full-time / Part-time

I work overseas for 2 months at a time, back in PA for a month. I am trying to find housekeeping support for my elderly parents who are no longer able to take care of household chores themselves. We can be flexible on the days and times. They need support with standard cleaning, and weekly laundry. For the times I am away, I'm also looking for someone who could help them with groceries or errands. I do this when I am here, but need help for the 2 months I am not. I appreciate that is perhaps not something this service includes.
