Need Animatronic / Robotic Costume Help

Hello all. I'm working on a project that I hope someone here can help me with. It's very complex and going to take a few years for me to complete. The project is an animatronic / robotic (either or both) centaur costume. The idea is to make it a one-person costume where the back walks with me as I move. It will also have certain preset-up movements linked to trigger points on the body. Such as, were someone to touch the rear-end, the tail will flick at them. I also want to be able to lie the body down on the floor while I'm in costume so I don't kill my legs standing all day. I'm playing with either having individual motors at each of the joints in the hind legs or using a cable, pully and gear system attached to the front legs (my legs) to drive them. I already have some drawings of my ideas that I've been working on but, since I've never done something quite this complex before, I'm hitting a bit of a road block. To be more specific, I have no idea what size actuators, servos or motors I'm going to need to make this thing move as naturally as possible. The frame will be aluminum and the hooves will be pine with some light stuffing and fake fur over it. I have no idea how heavy it will be. I will add the drawings as soon as I have them finished. Any help would be greatly appreciated.

or search other animatronic.  Could adapt that to flick the tail.
