Realistic Head Swap for Brochure

I need a skilled retoucher to replace the current head on a stock-style photograph of a worker wearing a hardhat with my own head, making the result indistinguishable from an original photo. The finished piece will go straight into a professional company brochure, so skin tone, lighting, shadows, and perspective all have to match perfectly—no visible seams, halos, or cut-out edges.

I’ll supply a high-resolution portrait of myself plus the target hardhat image. Please return:
• a flattened, print-ready TIFF or high-quality JPEG in CMYK at 300 dpi, sized for an A4 layout
• an editable PSD with all key layers intact (masking, colour grading, adjustment layers)

The image must hold up when printed at full page size, so advanced compositing skills in Adobe Photoshop, precise colour correction, and subtle sharpening are essential. If you can meet these standards and turn it around quickly, I’m ready to get started.
