One of the things you might do is if you're actually loading aircraft each day is to go up to the cockpit and meet the guys who are flying. There is usually a little dead time when they are just hanging out waiting for their paperwork and they would (usually) have time to talk with you. Let them know of your plans and ask their opinions. If you load the same flight each day, more than likely, you'll run into the same guys on the flight deck fairly often. You might develope a relationship that way. It's worth a try. And if you do find someone who is willing to give you a recommendation, be sure to get their business card. Good Luck with your plans.
