Hi Jason:
I have seen a demo for Gravity Forms and it might be able to do what you need. I use contact form 7 which is free and very simple. You might want to check out these plugin on wordpress.org plug in page.
Hope that gives you some options.

Thank you for the advice. I will check it out and see if that will work.

If you can’t find something that works, and don’t want to mess with the form code you could send all inquiries to one address and forward from there to secondary addresses based on some content, for example the subject line or one of the fields in the drop down.
