Agents looking to become Brokers

[Amorette Mason]

Hello BP!

When an licensed RE agent is looking to take the next step to become a broker, how do they usually go about this process?  I've seen listings on Craigslist where companies offer agents incentives to join their company and become a broker, but other than that, I'm not sure where they would find these opportunities.  Is it usually done through networking?  Are there other websites that I don't know about?  Would a head hunter be an option?

Any feedback is appreciated.  I'm very green on this subject.

Thanks!
