SW3 - skill tree and help needed

[Raga]

I don't want to start a new topic so I am asking here.

Is there a way to earn noney outside the main plot?
How to trigger random missions?

When I was playing on hard difficulty I was given 2 missions from Patrol Stations to hunt pirates for 10k, but nothing like that occured on medium difficulty.

I remember that there were some missions on station in SW2, but here I cannot find any.

Any advices?
