Given that you're working with varying numbers of records per page, you may be able to use Word's Catalogue/Directory Mailmerge facility (the terminology depends on the Word version). To see how to do so with any mailmerge data source supported by Word, check out my Microsoft Word Catalogue/Directory Mailmerge Tutorial, in the 'Sticky' thread at the top of this forum:
Microsoft Word Catalogue/Directory Mailmerge Tutorial
The tutorial covers everything from list creation to the insertion & calculation of values in multi-record tables in letters. Do read the tutorial before trying to use the mailmerge document included with it.

For some recent, worked examples, see the attachment to the posts at:

Alternatively, you may want to try the Many-to-One Mail Merge add-in from Graham Mayor at: Merge Many To One
