Enhance Outdoor Image with 3 People

I need a skilled photo editor to add three individuals into an outdoor image (which already has a person), making it appear as though they were present at the time the photo was taken. This project is for personal use, and the added figures should blend into the scene in a casual and natural manner.

Ideal skills and experience for this job include:
- Proficiency in photo editing software (like Adobe Photoshop)
- Keen eye for detail to ensure the added people match the lighting, shadows, and overall tone of the image
- Ability to create a natural and casual appearance for the added figures

Please provide examples of similar work if available.
