Photo Editing: Outfit Change & Background Swap

I need two pictures edited:

1. First Picture:
- Add my face to this picture.
- Change the color of my outfit to black.

2. Second Picture:
- Add a side profile of my face.
- Change the background to a desert scene, preferably the El Paso Transmountain area.

Ideal Skills:
- Proficiency in photo editing software (e.g., Photoshop).
- Experience with color changes and background modifications.
- Attention to detail and ability to create realistic edits.
