Ok, the trade is that this mission gives a badge, Spelunker, as reward for being part of the group completing the mission. That badge is needed for the Atlas Medallion, a mix of badges that give a permanent boost to endurance.
Not everyone get's that missions, and it cannot be received at later levels, so many people find themselves needing it later in the game.
As such, your part of the trade is simply to allow him/them to do the mission with you. And for the possibility of getting the Atlas Medallion, exemplaring and giving some time, help and advice is a very good trade for pretty much everyone.
