Hello.
Your job captured my attention. I´m an experienced 3d animator, and I do most of my work with Blender. You can see some of my work at my demo reel:

I just checked your attached blender file. I think overall it looks ok, but lighting and texturing can be improved. Also, I would redo the animation, so it looks like they are dancing on the room.
As for your description, I will send you screenshots of my work, as well as a description of the techniques I will be using on the animation.
Looking forward to work with you,
Kind Regards
Eddie.
