undelete large files in linux partition

I am looking for an experienced Linux user to help me undelete several important files from a xfs partition. These files could be photos, videos, documents or anything else. The type of file or their exact location on the partition is unknown. I'm looking for someone to utilize whatever tool necessary that can recover the files - such as extundelete, scalpel or photorec. Time is of the essence so please respond promptly if you think you can help. Thank you.
