Photo Editing - Merging Grandparents' Pictures

I'm looking for a skilled photo editor to merge two pictures of my grandparents into one. The final image should be realistic, with both of them smiling. Additionally, my grandpa's face needs to be moderately enhanced for clarity, as it is currently a bit blurry. The original backgrounds of both pictures should be blended together seamlessly.

Ideal Skills:
- Proficiency in photo editing software (e.g., Adobe Photoshop)
- Experience in merging photos
- Ability to make edits in a realistic style
- Attention to detail
