I'm confused, you have ten vans running freight for other companies but don't know what kind of places to aproach? That's kind of like saying, I mow lawns for some other companies but don't know how to find people with grass in their ysrd.
You want knowledge, spend the money to join industry...
Saved an industry using other people's money, taking dollars away from shareholders and selling one to foreign interests. The auto companies would still be here today if he had done nothing.
