If you follow the link you will see there is actually a "National Cleaning Week", which seems to coincide with a time people do a spring clean of their homes.
The company in the link seems to have latched on to the idea and called it "National (Carpet) Cleaning Week", very enterprising seeing they are suppliers of carpet cleaning machines and products.
If you take a look at what they suggest is done - its all to be done by YOU, not by them. Everything YOU do may generate business for them of course, you promote your business, get more sales, use more products, or even buy a new machine, hopefully from them.
Doesnt mention a third party doing the leg work Ryan, its all about YOU promoting YOUR business, emailing your clients, contacting all your referals, contacting your local press, donate to charity (letting your clients know that a % of their purchase goes to charity, facebook/twitter, contacting local radio and tv stations, and so many other ways.
All good stuff and worthy of note, but it is all done by YOU.
