This is quite straightforward: I want a MediaWiki wiki running on a VPS box that's running CentOS. I'm running into trouble making all the pieces go together, and have no experience with Apache configurations and so on. If you know this, it shouldn't take more than two hours. (You'd be given the root password so there's no encumbrance.)
Candidates should have experience setting up database-backed websites based on existing packages, preferably with MediaWiki itself. As this is an unambiguous requirement, I'll let the job posting sit for 8-12 hours and choose a contractor.
