3D characters designed for e-learning game with simple repeating animations

We need four high quality 3D characters to be created for an e-learning game which will run on desktop and mobile devices.

The time frame is short, they need to be completed by the end of the week.

The characters are based on four real people who appear in the companion e-learning videos. The goal is to have 3D representations of the four people created accurately enough so it is clear they represent the people in the videos.

They should be wearing modest, casual attire, appropriate to their age, gender and style as in the video samples

The characters should have reasonable facial detail as there will be some close up views during the game.

We have used iClone Character Creator in the past and found the quality/detail to be good and is the level we are looking for in this case

The characters need to have two simple looping animations: "standing idle" and "sitting talking". These can just be stock animations.

The characters will be imported into Unreal Engine 4, they should be in FBX format for transfer. There is a benefit if all characters use the same skeleton.
