Hi there Bajabuddie and welcome to the Q&A Forum!
You have a few options. Check if your publisher program saves a document in the Adobe PDF format. Many pros send proofs to their clients in that format. If so, let me know and I will give you suggestions about how to set the preferences to give you much smaller sized file suitable for proofing.
I sometimes use OpenOffice by Sun Mircorsystems, a free, open source program that lets me open Microsoft documents such as Publisher. My Microsoft Office is old so I open a compatible document in OpenOffice and Export as a pdf file.

http://www.xdrive.com/There are similar free services, though this is the one I'm personally most familar with.
Alternatively, if you have your own website, you can FTP the file and give your client the URL to the file so he/she can download it.
