Carpentry and Woodworking - Find or make victorian style casing?

I'm searching for a door/window casing very similar to what I have posted at:

I want the same thing, but not as wide (scaled down to about 3 inches or so). I've looked around a good bit myself and called a few places, but so far have been unable to find what I want. Has anybody seen this style of molding in a smaller size? If not, would it be feasible for me to make some of this myself? I only need about 30 feet of it.

Any help would be appreciated. Thank you.
