Window cleaning for 2-story home with large panes

I'm looking for a reliable cleaner to wash all interior and exterior windows on a two-story home. The property has large glass panes, including bay windows in the living room and multiple upstairs bedroom windows. Please provide your approach to safely accessing higher windows, any required equipment, and whether you use eco-friendly products. Assistance with sills and frames is a plus. Ideal timing would be a morning slot on a weekday, but I can accommodate weekends if needed. The job should ensure streak-free results and careful handling of delicate window treatments.
