Well,.... the best way could be a bribe but they are Rare.

So the next best thing is to look on the jobboard if they have any missions to
offer. the more missions you do for them the betterr the alignment with them,
but usually (my case) one mission is enough if you're neutral with them

after that they will probably give you a mission to deal with (small, about level one)

the better you get with them the more cash you can get with them
