Photo Editing - Remove Background Figure

I have a medium resolution photo set in a complex scenery background. There's a person in the background that I need removed from the photo. The editing should be seamless so that the removal does not detract from the overall quality of the image.

Ideal skills for this job include:
- Proficiency in photo editing software
- Experience with complex background editing
- Attention to detail for seamless edits

Please include examples of similar work you've done in the past.
