Building models & skins needed.

Ok, I need some buildings and such for something I'm working on... First off... I need 5 custom castles... but first... I need a Town hall for each so that it upgrades... I want 4 upgrade stages...

Example... Model 1(1st level) > Model 2(2nd Level) > Model 3(3rd Level) > Model 4(final stage) I doubt anyone will do all 20 but the themes I need are...

An anchient castle with moss running down it, some broken walls and such...

A forest kind of castle... be creative... Have some trees growing in to hold the walls up or something.

A undead kind of castle... just a darker scheme no bone walls or anything... Ok just an evilish castle nothing undead or gory.

Your regular run of the mill castle... make it much more detailed then the normal and much bigger without looking like shit...

And last but not least a castle with snow, and ice on it... not to much just like it's an actual castle thats been snowed on n such..

Also... a more lifelike-realistic barracks model.

I need some new tree skins and models if anyone feels up to it... I want a large willow tree, a few pine trees... couple snowy trees... just a variety from the old basic trees.

If anyone is willing to do this models, or skins if you can pull it off with only a skin... Model files I want between 400-1000 pixels.. so feel free to make this stuff detailed. And if anyones up to it I'll be needing some unit models and skins soon, pm me or post here if you're going to do any of these.
