I think you're missing my point that C-130's won't be doing private cargo transfer's. These are, for all intents and purposes, military only aircraft.

No, there are a C130s in civilian service.

Lockheed also makes a civilian version of the C130 called L-100.

And they've announced a new civilian version based on the C130 Super Hercules called the LM-100j.
