I think I am going to give walletrecoveryservices.com a try (Dave Bitcoin).
He charges nothing if unsuccessful and 15% if sucessful.
15% is only if the wallet is worth more than $100 000, and if the whole procedure can be completed in one week. Everything else is charged with 20% of what is recovered.
Our standard fee is 20% of the value of the wallet, only if we are successful. Zero otherwise
If your wallet is valued over $100K USD, then we offer a lower fee of 15% for an initial phase of tests.
(generally takes around a week).
If that fails, it indicates the password is more complex or uncommon. We will reach out to you to discuss reverting to our standard fee for further rounds of attempts.
If he scams me, I will let Stephanie know, and let her broadcast it.
I have no personal experience with him, but I have never read that anyone has complained about his services - the man has built a reputation that certainly brings him a very nice profit.
