3D Character Storyboard, Modeling & animation with realistic effect

Information for the business: We create online games
Design details: An angry villager who carry a pitch fork. He is one of the main characters. He is very angry and wants to defeat Dracula. He should have multiple grunt sounds we will provide all sounds for him. The animations are open for interpretation, he should be looking over his left shoulder as if he is looking back at the game, and back at the main camera.

First create a storyboard of the character with all face expressions with different T-pose (front, back, left & right views), second step create model in Maya software, add Zbursh sculpting, add UV texturing in detail & lightning. Third step to create animation according to the storyboard & fourth step render & provide the final output in png sequence & mp4 format in different sizes 256x256 pixels & full pose of the character.
Important points to be noted - convert into a low Poly FBX model, details are added through sculpting & use normal maps created by the sculpting tool, therefore no polygons are involved. The final model needs to have PBR textures to be used in Game

The Character must be exported as an FBX with the Textures Embedded ( maya 2015 has a game export option to do this)

So, character should look realistic texture and lightning should match the background. Check the expectation output attached image reference. Need such kind of output.

Following software should be used to do modeling the character:
1) Maya
2) Zbrush

Requirements:

5 animations without lip sync
5 animations with lip sync.

Lip syncing must be done with bones and NOT BLEND SHAPES.

This must be also converted into a low Poly FBX model not exceeding 5mb in size inclusive of textures and animations. Each animation should be a separate FBX File.

Also an animated icon (1 second in length) needs to be created out this character, 256x256 resolution size.
