"Sponsor a (paper) Book."

Check with local arts/crafts organizations for a calligrapher. Find someone who has a good track record and can provide references. Negotiate a good rate -- preferably "per piece."

For a reasonable donation, the calligrapher will write "This book sponsored by:" followed by the sponsor's name. (Obviously, using acid-free, archival ink.) Make sure the donation more than covers the cost of the work. Solicit local businesses as well as patrons.

I've never tried anything like this, but it was the first thing that came to my mind. Good luck.
