My current job contributes positively to society, but I would love to have a job like this. Long ago, I joined the military because I naively thought we could help put a stop to human rights abuses around the world (too young and stupid at the time to realize we were only going to make things worse). So, this would be something of a dream job for me. I would even do it for a compensation package that's slightly below market rate. However, I couldn't justify either to myself or my family, financially crippling the rest of my life by taking a job significantly below market rate with little or no benefits. If I could do it all over gain, if I were young and single I would much rather have spent my military years working for an organization like yours. However, I have too many responsibilities at this point.
On a positive note, I think if you found a way to establish some kind of a part-time volunteer effort, many people would be willing to help for free. It might be difficult to manage, but I think it could work. I'd even be interested in volunteering at least a few hours a week (although my coding skills are approximately at the level of an intern.)
