Read everything you can on this site, especially the "Newbie" and "Ask the Recruiter" fora, until you feel your eyeballs will fall out, and take note of the things you would ask any potential carrier. When you have the questions, call the recruiters and ask.
Plan to attend the MidAmericaTrucking Show, (usually abbreviated as MATS), March 22 & 23, in Louisville, Ky, if you can possibly get there. A portion of the huge Exhibition Hall is dedicated to Expediting, and there will be seminars, carriers, and vendors galore, not to mention the staff & assorted mods from this site - we love it, it's a blast!
Also, check the Home Page on this site, for upcoming seminars: they're quite informative, and free - an unbeatable combination, no?
