I can help, if it's dedicated.
Time zones and all.
I hate MOST exterior work.
So give me an empty whatever and I'll love filling it with detail work.
Its not that I wont do exterior work, it just wears on my patience after a while ya know? and I'm not that good at it :C
I do like terrains though.
Let me know if you need a grunt to just help put things together, etc etc. Good luck!
