Realistic Photo Editing: Family Keepsake

I need a skilled photo editor who can seamlessly combine two photos: one of my late grandfather and one of my father. The final image is intended as a memorial keepsake.

Key Requirements:
- Mix the photos into a realistic style, not artistic or vintage
- Set the combined image against a backdrop of the family home

Ideal Skills and Experience:
- Professional photo editing experience
- Proficient in using photo editing software
- Previous experience in creating realistic photo montages
- Sensitive and respectful approach to editing memorial images
