Jobs of this kind are found in just about every industry and sector you can think of. Real estate, automobiles, retail, computers...this barely scratches the surface of your opportunities. and the temptation to push beyond ethical boundaries. On the other hand, if you can learn how to put yourself in the shoes of your customers, you can develop a reputation for being a helpful problem solver who earns his or her keep by consistently providing useful solutions.
