Photo Manipulation - Add Person

I have a photo that I would like to have someone added to, alongside me. I have the image of the person to be added. No additional enhancements are needed on the photo, just the insertion of the person.

Ideal Skills and Experience:
- Proficient in photo manipulation software (Adobe Photoshop preferred)
- Experience in photo compositing
- Attention to detail to ensure a seamless integration of the two images
