You might want to contact Landstar Express America if you have the minimum 6 months required experience. Their recruiting HQ is in Jacksonville, FL. I don't remember the recruiting number, but you can contact operations at 800-425-5277 and they can transfer you.
One of their top agents is in College Park, GA. You may want to contact them to get their input on the way agents work with owner/operators. They are at 800-307-7776. Tommy is a good person to talk with in atlanta.
LEA works through agents rather than through central dispatch like most expediters. It takes a little adjustment working that way, but for a team this can be a good arrangement.
If you consider signing on with LEA be certain you have a good anytime/anyplace (no roaming or long distance charges) cell phone plan.
Good Luck.
