Professional Image Editing Required

I have two pictures that need professional editing. The tasks include background removal and color correction. I'm specifically looking for a high-contrast look in the color correction. After the background is removed, I want it replaced with a new image.

Ideal skills for this project:
- Proficient in photo editing software like Adobe Photoshop or Lightroom
- Experience with background removal and color correction
- Ability to create a high-contrast look
- Creative with sourcing and implementing new backgrounds.
