Forensics has always been a popular field- anyone remember Quincy? It is very very difficult to get an entry-level position. One of my coworkers sent out over 400 resumes and went on over 50 interviews before finally getting a job. And it really doesn't pay THAT well. Most jobs are with municipal or state labs, so they are civil-service jobs. Don't get me wrong, we make decent money, but no one is getting rich doing this.
As far as the squick factor goes, like I said we are rarely at the crime scene or the autospy. Most of what we see are small pieces of evidence, clothing, footwear impressions, sexual assault kits, etc. I mean there is the psychological factor, knowing that you are working with evidence from a violent crime, but most of what we see isn't disturbing or gross in any way.
