Hello, I got one wallet.dat containing 3.5BTC and the password is 4 to 8 digits numbers and letters only, pretty easy one.
If it's a pretty easy one, why don't you pay a wallet recovery service to do it for you? The most reputable I know is
walletrecoveryservices.com. Dave, who's the administrator, takes only 15% of what's found for amounts greater than $100k.
It's already late, but if it's indeed easy, don't expect someone to send you more than a tenth of it.
