High Detail Cartoon Character Rig

I have a set of polished 2D concept images and I want them brought to life as a fully-rigged, game-ready 3D character. My preference is that you build everything in Blender; that is the tool I am already using for the rest of the pipeline. The final asset must fit a cartoonish aesthetic yet hold up in close-ups, so I am looking for high-detail sculpting, clean topology, UV-unwrapping, PBR texturing, and a robust bone rig that will import into Unreal without a hitch. You will receive model sheets, colour references, and a short animation brief the moment we get started. I will consider the job complete when I can drop the .fbx into Unreal, apply my existing animation blueprint, and see the mesh deform correctly with no weighting issues or texture glitches. If you can also include a quick idle or walk cycle as proof the rig works, even better. Let me know how many days you need for modelling, texturing, and rigging, and link to any cartoon characters you have already shipped in a real-time engine.
