3D animated character required

I require a simple 3D walking, talking, animated character.

It is required for an explainer video, which I am putting together.

I already have the background scenes to use (see attached examples). Also attached is an example of the character I want (but I want it in 3D) and I need the animated 3D character to stand and talk... or walk & talk in front of my scenes. The character needs to overlay my background scenes ideally.

I will supply the script and background scenes.

Please send examples of your previous 3D animations if you reply.
