Mail merge numbered ballot papers

I’ve just been asked to find out about organising a ballot on very short notice.

The position is that very close to the closing deadline, we have recieved a challenge to one of our elected officials, or at least I have only just got to know of it.

This means that individually numbered ballot papers have to go out to just under 1000 people, and the quickest way of doing that is to send the ballot papers as individually numbered attached documents by email. The attachments would need to be protected so that it has to be printed out and filled in by hand, it can then be snail mailed back.

I have Office 2003 - and I don’t know anything about macros, at all.

I suspect that it will involve mail merge, which is something else I know nothing about.Any help would be gratefully recieved.
