I have been using the PDFLib module (see this web site) to generated PDFs on the fly -- it works great, though it is commercial software. They also sell something called PDI (PDF Import library) which will let you open an existing PDF and retrieve particular page numbers. (The client didn't purchase PDI; I'm just going by the documentation.)

From there, it's probably five minutes work to write a small utility that opens an input document, retrieves a particular range of pages and writes them to an output document.
