Need to know the top ten(10) industries that produce document output
(companies that output the most on consumable products (paper, film, &
other media)).  After the top ten are found I need to know how they
measure up to one another from greatest to smallest. I have several
already but need to find the others.
 
Legal Industries (Law Offices)
Digital Graphics (Sign Shops & Advertising)
Architecture, Engineering and Construction 
Real Estate Companies (Corporate & Residential)
Educational Institutions (Private & Public)

Thanks,
iiikan

PS: There will be more info needed (related to this research) as I
report, so keep watch for future posts!
