Bullhorn Reach is:

This is awesome! I've been looking for a solution to do this for a while.

-I would build this on top of an existing job board platform. There are plenty out there, no need to reinvent the wheel.

-Include job description summaries on your site - use some kind of onmouseover div if you don't want to clutter the page.

-Have you considered scraping from other startup job boards out there?

-How are you planning on monetizing the site?
