Black and White Photo Restoration and Optional Colorization

I need an old black and white photo restored. Specifically, I require image sharpening to enhance:

- Facial details
- Overall clarity
- Background elements

Additionally, I would like to explore optional colorization for the photo. Please provide separate pricing for:
1. Black and white restoration only.
2. Restoration with manual colorization.

Ideal skills and experience:
- Expertise in photo restoration
- Proficiency in working with black and white images
- Manual colorization techniques (not solely AI-based)
- Attention to detail

Please provide before and after samples of similar work.
