Once again, I find myself recommending the blog Mailanka's Musings,
this post, "The Psi-Wars Process" especially, here.
If you're interested in this, you might take a look at the
Psi-Wars Wiki and at
the catalog of world-building entries on the blog.
PS. Psi-Wars includes a bounty-hunter template and a lot of blog entries on using them in a sci-fi game.
Good luck!
