I’d like to announce the launching of WikiWorks, a new MediaWiki consulting company that Yaron Koren founded. WikiWorks handles all aspects of wiki creation, from hosting to software installation to skin creation and other graphic design to data structure. As you might expect, the focus of the company is on Semantic MediaWiki and its related extensions; though they also handle regular, non-semantic installations.
You can read more (though, at this point, not much more) on the website @ http://wikiworks.com/
Thanks for the plug!!
