Hello! I saw your project and I'm really interested.
I am a profesional 3d artist, with lots of experience. I'm sure I can help in lot of ways. As you mentioned, I don't bid on this project for financial interest, just for the experience's sake, plus, I love games, and I want to use any opportunity to take part in making them.
What I CAN do:
1. Create low/high poly models, clean and beautiful topology, no overlapping, strictly in Quads.
2. Creating shaders, normal, diffuse, specular, bump and displacement maping + some easy textures (I'm not good at painting)
3. And my favorite: Animation! Character or object, anything, any kind of animation!
What I MIGHT do: Rigging. I have tried it, I'm not super good at it. But still, I could give it a shot.
What I CAN NOT do: Coding. I have never made one, I can not do one, I might never be able to do one.
I have a little experience in UE4. Mainly environment creation. I know how to import mesh, create and apply shaders. How to navigate and manipulate enviroment inside UE4. Plus, I have tried Unity. I'm not very familiar with it, but I bet it won't be harder than UE4.
Anyways, I would love to help and take part in this project. I'm from Georgia (east europe) and I'm available almost any time (I have full time job but have lot's of free time in my hands).
Hope hearing from you soon!
Even if you don't, I wish you best of everything in your project.
And thanks in advance.
Regards!
