Photo Editing: Remove Two People

I have a simple and plain picture of my Father which requires some professional editing. Specifically, I need two people to be edited out from the image. The background is not crowded and should make the task simpler.

Ideal skills for this job include:
- Proficiency in photo editing software
- Experience with photo retouching
- Attention to detail

I am looking for a freelancer who can ensure the final image looks natural and seamless.
