See this answer by Robert Cartaino:
We no longer offer a subscription service nor license the software to host Stack Exchange sites. Stack Exchange sites can only be created through the democratic, community-driven process at Area 51. You can read about that process here: Area 51 FAQ.
We do not offer “white-label” services, nor the ability to bypass Area 51 to create sites through partnerships.
Check out some open source alternatives instead of spending some money on a license. This meta link has a lot of info.
I've personally tried OSQA and tell you that it is very easy to setup and implement! Give it a shot!
