So the buildings I scrounged up from local thrift stores just before Christmas time. If you look really closely you can see most of them have Christmas Wreaths on the door ways. Companies like Lemax, JC Penny, Sears, and such have been making them for years, but new they're easily $40 each. If you can find them, I'd suggest getting them at Goodwill, the Salvation Army, or Arc thrift stores. I don't know what you'd have in your area. I'd suggest taking a single easy to carry model (fits in your pocket without stabbing you in the leg) to make sure the size is right. I was pretty picky about the scale, but you have to be a little forgiving.
I did find a nice set from the Home Depot that had a bunch of buildings, fences, and cool gas lights that actually light up and I think it was only $50, but obviously most of these will be seasonal. I like going right around the end of October, the stores are usually bringing them out by then around here.
So to give them the right look, you'll need a satin black polyeurothane, just wipe the whole thing down with black to give it a more gothic appeal, and cover any "snowy" bits with green flock or sand. It's pretty easy, and just takes a day or two for that stain to dry. I didn't try to cover any lightbulb holes, or get too worried about dents and scratches. Each piece will be a work of art so you'll have make the decisions about each one at a time.
The Graveyard set came from Games Workshop, but I can't remember the name right now. I keep two churches with different looks that are porcelain around as well.
