The bad thing about Trade and Recruitment is that very few of the missions give a lot of cxp, because they give other rewards - commodities, doffs, or loadsa dil. Really annoying.
Trade: the best consistent one is actually the Turn In Contraband, which also gets you a pretty good amount of dil.
Recruitment: apparently you can dismiss doffs for a tiny bit of dil and a semi-decent amount of cxp. Test it out, and maybe turn those whites into something useful.
