cryptsetup luksFormat on sdx3 with default parameters over an existing partition with (I think) the same parameters but a different passphrase. Realized my mistake shortly after typing "YES" and I don't think further writes happened since.
Like mentioned in other comment, I'd def shell out a portion of the money to recover the rest but not sure where to start. Given the amount I'm hesitant to do any further operations myself with the drive (Samsung evo SSD) plugged in.
I'm not in a position to advise, but I'd try a few recovery firms- given the context, they should be able to provide realistic estimates on what's possible. Even if it's 10% of whatever is inside if you are successful.
