Creation of a 1/10 scale visual

Hello,

I need to create a frieze that is 3 meters long by 30cm wide, which will be printed on a pop-up tent. The visual will be a montage of several cut-out dog photos, with a background, and the breeding name.

Here's my problem:
How do I set up Photoshop (or Illustrator / InDesign) to create the visual at a scale of 1/10? Should I create a document of 30x3cm at 750 dpi?
If so, should the photos used for the montage also be at 750dpi upon import? Or can I leave them at 300dpi and import them into my 750dpi document?

Please note: I am working with the Adobe suite from 2019, and my computer is not powerful enough to export a final file in the format 300x30cm.

If I need to use Ai or Id to create the visual, how do I change the resolution from 300dpi to 750dpi?

Thank you in advance to those who will help me!

Configuration: Macintosh / Chrome 91.0.4472.114

    This is the kind of work that is done at a scale of 1:2 or 1:3...

    You cut out your images in Photoshop and save them as PSD with the clipping mask. You keep a resolution of 300 dpi at the scale....
    When printing, you will enlarge your resolution will drop in relation to the scale. For a scale of 1:2, your resolution will change from 300 to 150 dpi, but in fact, it's not a big deal because given the distance at which your strip will be placed, the lack of detail will not be very noticeable. Eventually, you can push your resolution to 450 dpi if you are working at a scale of 1:3.
    This implies, of course, that you have very high-resolution images to start with. Ideally, you would have RAW files...

    Once your images are cut out, you do your layout in InDesign. This way, you limit the size of your file to the presence of the images. The text, color areas, and icons being vector, do not add much weight to the file.

    For the service provider, save as PDF without resampling options (you may need to create a new profile if you don't have one). and with ZIP compression (absolutely not JPG).
