Contact Form – option for multiple authors?

My blog is becoming quite popular (https://www.avalon5.com) and several new people have requested access to post their own articles on the site. So now I’m expanding beyond just myself and as “Howl @ The Moon” grows I was wondering if anyone has seen a plugin that does this, or can suggest how I can modify an existing plugin to achieve it…

Basically I’ve got a “Contact Us” form setup as a static page on the site which works perfectly. Now that I’ve got multiple authors working, I need to give the option to contact one of several people (drop down box?) without giving away their email addresses. So I guess what I need is the ability to drop down a list of their nicks/aliases on the site and then have the form email to the right person.

Anyone seen this in action? Is it hard to do? Thanks in advance for any assistance.
