Realistic Photo Colorization

I need a skilled artist to colorize 1-5 photos. The colorization should be done in a realistic style.

Ideal skills and experience:
- Proficiency in photo editing software (e.g., Photoshop)
- Strong understanding of color theory and realistic shading
- Experience in colorizing black and white or vintage photos
- Attention to detail and a creative eye

Please provide samples of previous work.
