Realistic Group Photo Creation

I'm seeking an experienced photo editor to create a realistic group photo from separate images, set against a natural beach background. This image will also include two deceased individuals; I have black and white images of them that need to be restored to color. This colorization should include additional artistic enhancements.

Requirements:
- Combine multiple photos into one realistic group photo
- Colorize black and white images with artistic enhancements, including:
- Facial features
- Clothing
- Background elements
- Depict deceased individuals older to match current group members
- Natural beach background
- Final image in JPEG format

Ideal Skills and Experience:
- Advanced photo editing and manipulation
- Expertise in colorization, especially for black and white images
- Strong artistic sense for enhancements
- Proficient in creating cohesive and realistic composite images
