Let's see. If you are doing it to make money, get the licence (hee hee hee). I expect, but don't know, that you would need a business licence, a properly zoned location, a commercial building (anyone here legally load commercially in their residence?), a powder magazine, and oh I am sure the red tape spins for miles.
Or, buddy wants to pop off a few boxes of bullets, but has no gear, or perhaps no place to perform the nasty deed - some wives frown on clamping presses to the Chippendale dinner table. In which case, have him over, teach him how to do it using his components, your gear, and you keep an eye on him to make sure he stays on the straight and narrow. Normal gouge for helping a buddy is a cold one when it is all wrapped up.
Or else he is not a buddy, and you really are trying to make a buck which is back to commercial reloading.
