Hi,
I can do this job in a few hours. I just set it up with 1.22.6 and it all works, including images. Here is a screenshot: [login to view URL]
I have no server at the moment but I can set up a reverse tunnel to my local machine at an agreed time if you want to see a live demo.
I have actually set up VisualEditor recently to get involved with the development of it (I am the author of the MediaWiki Lingo extension), so I was pleased to see this project as soon as I signed up to FreeLancer.
Regards,
Barry
