Heyhey,

Might be able to help you out. I'm a security specialist and know a lot about brute forcing passwords, seeds and private keys.
I have no idea how to prove honesty. I just like a challenge every now an then, and read your post.

If you feel like it, send me a PM. Even if you don't trust the situation enough, I could at least explain your options and chances of retrieval. All free of charge.
