Dear John,

one option might be to convert the PDF document to postscript
(using ghostscript http://pages.cs.wisc.edu/~ghost/doc/AFPL/index.htm),

You can then select certain pages using psselect (which is part
of psutils (ftp://ftp.dcs.ed.ac.uk/pub/ajcd/psutils.tar.gz) , which contains also  pstops, which allows to rotate a ps file :

(assuming it started out being 8.5" wide):

pstops -w0 -h0 1:0R\(0in,8.5in\) input.ps > rotated.ps

Next, you would need to output the rotated file on a landscape 
page while converting it to pdf.  For a 11" W x 8.5" H page:

ps2pdf13 -g7920x6120 rotated.ps

(The units of measure are decipoints, where 720 decipoints = 1 inch)

Best regards,

Axel
