I am doing something similar but haven't got very far in finding someone to work with.
Ideally I'd work with just one other person to take on the task of enhancing textures.
I pump out ideas well, I have more than enough skills to model them, but I feel my texturing skills (in particular, creating a stunning normalmap) isn't quite there yet.
An example of what I can do on my own can be found here.
If you're interested in a joint venture with me please visit my thread then PM me.
If not then best of luck and I look forward to seeing your work on the Workshop.
