These people must be having limitation on clothes as people start to abuse if it is unlimited.I ran into this website. It seems that they will do laundry and they have monthly, quaterly and early plans for an average family. It is about 3000 for two adults and 2 kids below the age of 12. They will pick clothes from home and deliver back to home for free. Most likely it serves only in limited area, but looks good so far.

Earlier other service operators had the pinch and did limitation / cap on number or weight of clothes.
