Sanctum Arts came to my mind, too.  He no longer sells Poser stuff, but if you Google the name, you can see what his stuff looked like.

Personally, I did not buy his stuff.  It was very well-done, but so distinctive.  You could spot it right away, which, IMO, limited the usefulness of it.  I'd prefer something that I could put my own mark on more easily. 

But a lot of people loved his stuff and bought it, so maybe there would be a market for figures like these, too.

Also...the general style of these reminds of Poisen's work.  He does props not figures, but they are very elaborate like this.
