Create a 3 row, 1 column table. Set the top and bottom page margins to the minimum your printer will allow. Centre the table vertically on the page. Go into the table properties and set the row height to a fixed value. It will be about 8.9 cm (you will need to experiment with this) . Also in the table properties, you can hide the borders if you wish.

Alternatively, open a new document and search for "with compliments" in the Microsoft templates library.

Cheers,
