Photo Editing: Remove background face + Add acrylic nail

I need a photo editor to remove a photobomber in the background of one of my photos to make it look cleaner add in an acrylic nail in both images (missing on my middle finger). Make it appear realistic and natural in its placement and proportions.

Ideal Skills and Experience:
- Proficiency in photo editing software
- Prior experience with cosmetic or nail edits preferred
- Strong attention to detail to ensure a realistic final product.
