I have some experience making meshes in blender as well as maya and 3ds max (not my primary skill however). I’m most passionate about landscapes and level/world design. If you need someone like that I’d be happy to lend you my time even if this project doesn’t go anywhere. Here’s the largest terrain I’ve created using World Machine (not practical for your needs, but I love huge maps lol):
