Earlier quoted context omitted.
I'm (obviously) not the person you're replying to, but information security, financial analyst, systems analyst (ok, some basic programming skill required), systems architect, IT audit all come to mind. That's just within the scope of the jobs I've been asked to interview for within the last 3-4 months. I'm a CISSP with a couple years of infosec consulting & audit experience; I can read/write SQL, and that's about it…
Does that kind of auditing job tend to be freelance, or for a consultancy/agency?
In my personal experience, you don't tend to be too successful doing freelance security consulting unless you have a lot of certifications and you're aiming at very small companies. Bigger organizations will go with PWC, even if you're half the price.
