My freelancer mostly hangs around NY talking with people, occasionally getting hired by someone for escort or backup. Or he explores.
Getting the tag is a pain. First way I know: Get as many Zoner and BHG bribes as you can (double for both), then take BHG missions until your Freelancer rep is full green (by this point your BHG Guard will be as well), then drop all your fully green reps as normal leaving just Freelancer. You may end up having to kill BHG and Zoner Guard NPCs to drop those reps (and the BHG Guard rep) without affecting your Freelancer rep. Very time consuming, especially if you're in a crappy ship (Manchester for BHG missions, but a good ship does them faster). Impossible in a crappy ship if you need to end up killing Guard NPCs.
Second way I know: Double/triple Zoner bribes, kill Zoner Guard, more Zoner bribes. Expensive, and requires a good ship, but potentially much quicker.
I used the first method. Took me around 8 hours of missions and fixing, IIRC. I also managed to do it without having to kill any Guard NPCs, but I'm not sure how.
