While I think HN should have this too, I think you're setting that cost pretty low. I've often wished there was a way to post (non-YC, non-startup) jobs to HN. It would be at least as good as if not more effective than what you get from a professional recruiter. I'm pretty certain a rate of $1500 would be reasonable. Especially given the huge savings in time that I don't have to spend filtering the total bozo applicants.
