Realistic Face Swap Photo Manipulation

I'm looking for a photo manipulation wizard, ideally someone with a keen eye for detail and a knack for making realistic edits. You'll be swapping a face in one of my photos with that of a specific person I have in mind. The outcome should be lifelike and not over-the-top or cartoonish.

Key Project Details:
- I already have a specific person in mind for the face swap; you won't need to source or recommend anyone. I have few photos of him .
- The photo manipulation needs to be completed within a week.
- This project is for personal use, not for any commercial purposes.

Your Role:
- Execute a high-quality, realistic face swap in a photo provided by me.
- Ensure the final image looks natural and not overly edited.
- Be flexible with the resolution of the photos provided, as I'm uncertain about their quality.

Ideal Freelancer:
- Proficient in photo manipulation software like Photoshop or GIMP.
- Demonstrated experience in realistic face swaps.
- Ability to deliver quality work within tight timelines.
- Excellent communication skills to understand my specific requirements.

I'll provide the photos for the manipulation. I'm looking forward to working with someone who can bring my vision to life in a realistic manner.
