List of all carpet cleaning supply business? -

?

I suggest that you go to your local library. Ask for the reference librarian if you do not see a sign or something. Ask them the same question because many public libraries now have great databases that will cost nothing to access. You probably do not want a list of every carpet cleaning supply business in the country or world, but you should be able to break the list question down to a reasonable size, such as state, county, region, city. OK?
