How do you get people to see that you are wanting to sell them?

I just got to lvl 5. There is a list of players under the negotiations tab but I have no idea how they got there.

I have players people would want but they are Nordgens and I don't want to just list them for below value. You can't just go and find players like that all the time and if you do there are bidding wars. I want tokens for them.
