Secure Immutable Cloud Storage Setup

The task is needed to be started urgently and now. I need someone who can set up safe cloud storage in multiple services: google cloud; cloudflare non deletable, proton drive and maybe some more. Need a person who can create corporate account google for me and set it up all files to not be able to delete. And transfer all my files from my google drives to there saving metadata initial. And who can upload materials from flash drives to cloud storage. Also need to set up safe AI which will be working 24/7 and analyzing materials uploaded and it to be protected from MITM attack, prompt injecting. And to be protected from devices which were hacked and under MDM. Cloud files should be safe and non deletable / non changeable.
