Indoor Photo Editing Expert Needed

I'm looking for a skilled Photoshop professional who can expertly add a person into an indoor photo. The challenge is that the photo is set in a dim or low-light condition, so the added individual needs to be seamlessly integrated in terms of lighting, shadows, and proportions.

Ideal skills and experience for the job:
- Proficiency in Adobe Photoshop
- Proven experience in photo manipulation
- Strong understanding of lighting and shadow effects
- Ability to create realistic and natural looking images
- Attention to detail to ensure proportions are accurate
