Getting a Job Board up and running

Hello,

I've found that having a niche board and name that sells itself is critical. Can anyone explain the first few steps however to move from a beta site to a full board, such as what kind of developers and typical cost one should spend? I've seen quotes off market place boards such as Elance for about $4K. The name of my job site is simple and geared
specifically at MBAs that want to live and work in major citys. I'm not going to put the name up here, as this blog is for
more informational and original content. But my big question are this:

1) I've seen boards that charge the users or job seekers, and allow employers to post for free
2) Just charge on both ends, for job posting and job seekers to subscribe
3) Revenue based on ads

What is the way to go? I was looking to charging the jobseekers a monthly rate, and is there really any money in these
niche boards.. by that I mean can anyone tell me of a smaller job board they have or know of and what kind of revenue
they bring in? I really have no idea.

The name of my site and current branding just attracts MBA level resumes very easily and little advertising, simple fliers
in an MBA school for example will get a hand full of resumes in a day or two, and this is just in one school. So just by test marketing this, I know the site's current branding speaks to a real felt need in at least part of the target market.

If someone would like to critique the idea and train of thought that'd be appreciated.
