When I was working my company had an agreement with a dry cleaners to pickup laundry and drop off cleaned and pressed clothing twice a week. There was a designated location to drop off your large blue duffle bag and pickup your finished laundry. In addition to dry cleaning, they also washed and pressed shirts and pants. You would be surprised how many people brought in all their outer garments to be cleaned and not just executives. I also remember one man who wouldn't drop off or pickup his own laundry. He had his assistant call his wife to come from home to do that chore.
Also, many companies with large campuses, Nike comes to mind, have a dry cleaners/laundry business onsite so employees can drop-off and pickup the same day.
