I would think that TeX is an excellent writing programs but may be 
not too good for special demands a printing business has.

Or - if the single pages are needed for some kind of  projection - 
then the beamer.sty should be used.

But anyway: if you produce a ps-file with any number of pages, you 
can easily open it with Adobe Acrobat and save it just as single eps- 
or pdf-pages.
