Minimalistic Portrait Vectorization Needed

I have a photo of a person that I need converted into a clean, minimalistic vector illustration suitable for high-quality print materials. The final artwork must keep the likeness recognizable while stripping away unnecessary detail, focusing on flat shapes, balanced proportions, and a restrained colour palette that works well when scaled.

Please create the illustration from scratch—no auto-tracing—so I receive fully editable source files. On delivery, I need all of the following:

• AI (layered, CMYK)
• EPS (compatible back to CC 2020)
• Transparent-background PNG at 300 dpi
