She said it herself, she doesn't just take on those missions to see the end goal, often times she works for herself, she does things unorthodox in the name of having 'friends in high places'..~ The trade she normally gives is rather simple, really. She keeps any unsavory information you wouldn't want the public to know about well hidden and safe.. and in return she gets a bit of help from time to time. It's that easy..~ Plus, after a few favors are called in, there's the added benefit that those 'friends' she makes in high places get to enjoy those lavender lipstick marks on the pillar of meat that possesses all that power; getting to ravage the hispanic whore like some two dollar street walker for breaking into their high security facility~
