I was planning on doing similar work for my next, next project. I love what you're doing and agree with the mission (although, I think both the "which career" and the "how to get the career" are about equally taught, and horribly so).

As far as this specific implementation goes, I can tell you what I'd like for my clients. I'd rather have them start with a target income, then only consider jobs above that income... I believe BLS has ways to filter by the salary number, rather than job title, and I think it's essential for what you're trying to do.
