Clean email list and categorize only certain businesses with specific names - repost

I am looking for someone to categorize my database with the businesses to include only Print, Printing, Press, Graphics, Binding, Folding, Stamping in their names. I need it to be done asap and if you are good with Excel, it shouldn't take you that long at all. The list is roughly 1 million businesses in 30 separate files so I need someone with expert Excel knowledge to do this VERY quickly.
