One way is setting up a business page and using the publisher code on the index page of your site then set up profile pages for the writers with their g+ links using the "author" markup. In the articles, you link to the write's profile page inside your site while the writers need to link their g+ profiles in the "Contributor to" section to the index page of your site to "close the circle".
Most of our site's articles link right to the author's g+ page and it seems to work for them and us. The whole idea seems like a good idea since anyone who views a SERP that includes your writer might click the "More by..." link and run into your site by way of a completely off topic search.
