As a hiring manager, this does not make sense. Why should I pay $50 just to make initial contact with one person, and then still have to do the full recruiting and interviewing process?

Recruiters will do all that for me for free, and pre-screen everyone, so it is the same net result to me, at least on the front-end of the hiring process.

FYI, answering this question here isn't the point - your site needs to clearly tell hiring managers why it is better for THEM. You won't get a chance to open a dialogue with them when they view your site.
