Hi, I am expert C4D but what you are looking is almost impossible to do it with C4D, you need an expert on "unreal" or "unity", but the budget may be higher than your proposal.
Relevant Skills and Experience
The process is very time consuming, you must model everything with high poly, bake the object to save the good looking textures illuminated (materials) using maya or 3dmax.
Proposed Milestones
$1250 USD - NA
once baked you can upload and "program" the 3D low poly on the unreal or unity game engine.
