Realistic A4 Full-Body Sketch

I’d like a realistic, full-body sketch of my son on A4 paper. I’ll supply a clear reference photo, but please redraw him in a custom pose: standing so that both a hand and leg are clearly visible. A strong likeness and good proportions are important, yet I only need a straightforward black-and-white pencil rendering—no extra backgrounds or color.

Deliverables
• One neatly finished A4 pencil sketch on quality drawing paper
• A high-resolution scan (JPEG or PNG) suitable for printing

I’ll share the reference photo and any minor pose notes once we start. If you can ship the original, let me know your mailing location and cost; otherwise, a clean digital scan is acceptable. Please include a brief outline of your process and how quickly you can turn this around.
