I'd suggest not asking for custom animations + new model unless you're willing to commission someone.
Maya is basically the only one that will work naturally with Amnesia (I know, because I've been doing it...). You could, when Traggey finishes adding sounds to it, use the model he made and I animated for your character. It's supplied with textures already and custom animations, which I just finished about 30 minutes ago.

Have fun. It'll be posted (hopefully) within the next couple days. If I get the go from Traggey, I'll post it tomorrow, no sounds added.
