Hi,
I have experience with low poly modelling and animation in Blender, mostly due to using it in my own video game projects. I can model, pose, and even texture the character for you if you need me to.
Also, do you just need the soldier, or the aircraft as well? I didn't understand quite clearly. If you would need a fully textured aircraft as well, it would be slightly (20-25%) more expensive then my original bid. If you don't need it textured, I can include it in the original price.
