USA Bus Lines

Can anyone list all or most of the bus lines that someone could ride basically?

I have a friend who wants to know. He is low on money and has to travel from Indiana to Oklahoma, and later to New Mexico. And then a month later he has to go to Massachusetts. He's doing some kind of maintenance for some traveling show and has to get to the locations on his own.

1. I think Trailways or Greyhound (they merged several years ago) is the only nationwide bus line.
