Below are some ideas that might reduce the 'pdf' file size:

1. Check the size of every image that you insert into your document.
Are any of the images larger than necessary? - if so reduce size.

2. Do any of the images have higher resolution than can be reproduced? - if
so reduce the resolution.

3. Are images in compressed format? - if not convert to JPEG (ie '*.jpg')

2. Check compression settings in Acrobat. Set compression options to  'JPEG
High'.

George, why not send me a small (say one page and two pictures) sample in
Publisher format and in 'pdf'. Also send the pictures separately. I will
then see if I can produce a significantly smaller 'pdf' file of acceptable
resolution.
