Evacuations in stations that are Federal. Take a Python or Anaconda, strap it down to hold as many passengers as possible and DO NOT forget a heatsink. Inside those stations get HOT, very fast.
First time I did it I went in without one and it was expensive. Going in not so bad, once you land it will bring you into the hangar automatically and you won't take damage.
But leaving? As soon as that door opens you start to take damage, so I recommend ejecting the heatsink asap.
To get the missions you go to the station -> Passengers tab. Try to get the most amount of missions in a single run, requires some maths. Then you just take the survivors to the nearby rescue ship, hand them over, do repairs/whatever and repeat.
This isn't profitable. But it's good to grind rank, and more specifically a phenomenal reputation grind.
I just hope you don't rely heavily on docking computers.
