Zip .jpg files within multiple subFolders

I need an AppleScript to zip files (not folders) contained in several sub_subfolders. At the end of each day we have a main folder with a name like SR_2022_Oct_20 inside the main folder are sub folders for each senior photographed. Those subfolders contain multiple files and a sub_sub_ folder named jpg(whitespace prefixed). I need to zip the files that are inside each jpg folder, so it ends up containing the zip file plus the original .jpg files.
The folder structure looks like this:

main                # Format SR_yyyy_mmm_dd 
    ├── Senior1         # Format LastName_FirstName_ScoolCode 
    │   ├── \ jpg       # NOTE: whitespace as a prefix
    │   │   ├── one.jpg # All jpgs in that folder have to be zipped
    │   │   └── two.jpg # as "main/Senior1/ jpg/Senior1.zip"
    │   ├── one.CR2
    │   ├── three.CR2
    │   └── two.CR2
    └── Senior2         # Format LastName_FirstName_ScoolCode 
        ├── \ jpg       # NOTE: whitespace as a prefix
        │   ├── one.jpg
        │   └── two.jpg
        ├── one.CR2
        ├── three.CR2
        └── two.CR2

There can be 50 or 60 Senior folders in the main folder for each day.
The jpg folder has a space in front of the name
This is way beyond my limited scripting capabilities - any help is greatly appreciated.
