To add on to the above with my experiences, you're also gonna need four reliable people at a minimum for the workshop parties when completing ...whatever project it is you guys are working on at the time. They don't necessarily have to be crafting lifers, but when you do a workshop party, you will need four in the party. It's gonna require time and effort, but depending on what your airships/submarines bring back, you can make a pretty good profit. With the upcoming data server split, it's up in the air on how the economy will shape out for individual NA servers.
