Looking for a clearing house of people needing a car driven from one
part of the country to another.  In our case, from Seattle to Texas
(Waco)

momk,

My wife and I are planning a cross-country drive.  In my research, I
stumbled across and bookmarked the page
http://www.soyouwanna.com/site/syws/drivecc/drivecc.html.

On that page, they recommend the sites http://www.movecars.com/ and
http://www.shipcar.com/, and also looking in your phone book under
"moving" and "drive-aways".

I hope that is helpful!

To clarify my previous comment, you would drive a car as an agent of
the mentioned companies.  soyouwanna.com explains in greater detail on
the first link I provided.
