Robbie,
I don't know about what to charge but how are you going to clean them? I have seen videos of window cleaners cleaning 5 story high window wint DI water from the ground. I have a couple of tanks for di water but the job I planned on using them on fell through. With di you can clean with a brush and then rinse and your done.
