How can I recover files from an emptied trash can on a MacBook M1?

On the 23rd of August 2024, all the files on my MacBook Pro 2022 M1's desktop were moved to the trash can and then deleted. The folders contained two years' worth of my work and personal documents. My life is now in shambles. I've already discovered the following: 1. No copies can be retrieved from iCloud, and third-party apps like Disk Drill or Tenorshare are unable to do so as well. 2. A recovery firm has informed me that it's impossible to recover files from an M1 with SSD disks involved. Question: Is there truly no company or tech person in the world who can recover these files? I'm not a millionaire, but I'm willing to go to great lengths to retrieve my files. Please advise me.
