3D Modeling and rigging of 2 humans from pictures

I need two kings of Swaziland 3D modeled and rigged, supplied as FBX models for Unity so that we can animate them in Unity. The clothing and body physique should match how they look in the pictures as the clothing and dress needs to be relative to the Swaziland culture at that time. 1 is a recent king and the other is a old past away king. I require the faces to be realistic as possible and to match what they look like in the photos, we have 6 pictures attached for your reference (3 of each king) and these need to be used (nothing else is able to be sourced).

Requirements:
- Use provided pictures for reference.
- Create human-realistic faces.
- High detail with realistic textures.
- Unity compatible

Ideal Skills and Experience:
- Expertise in 3D modeling and rigging.
- Proficiency in Unity.
- Experience with realistic human modeling.
