I'd be glad to join ye, good sir.
I'd say my terraining skills are a notch higher than the stuff we see on current maps, but it may be me being smug. Here is a screenshot of one of my works - Its a bit old, and I have improved a bit since then, but 'tis the only terrain screenshot that I had finished at the time.
I would've made that into a 'pull-down' image, but I don't know the BB-code.
As for modeling I can make some very nice edits on models, or splice them together to make something nice.
Then skinning, I'm not the best, but I can make Orcs/Uruks/Haradrim, never tried making a goblin or troll before, though.
