I can't do laundry ever again. I have fully bought into wash and fold. It's a total no brainer. For $25 I just got an entire hamper worth of mixed laundry washed and folded for me. The time and economics make it totally worth it.
I would definitely want to offer wash and fold service.
Privacy is important. I don't know that an "upholstered partition" (http://static2.businessinsider.com/image/5a501548c32ae61e008...), which honestly reminds me of the doors of American bathroom stalls, offers enough of a sense of privacy, especially because of sound.
