Portrait Background Removal - 20 Images

I'm looking for a professional who can remove the backgrounds from 20 of my portrait images.

Requirements:
- Backgrounds should be removed and replaced with transparent backgrounds.
- The level of detail for the background removal is intermediate. This means dealing with more complex shapes and finer details, not just simple shapes and smooth edges.

Skills and Experience:
- Prior experience in photo editing and specifically background removal is essential.
- Proficiency in using editing software like Photoshop.
- Attention to detail is crucial, as some of the images may contain intricate shapes or fine details.
