This may sound strange, but there is a 'certain' website which sells old Wallets and with it old private keys - I would purchase one, empty it out and then pass £120 worth to the person who helps me out (I have an Electrum Wallet, by the way, therefore I hope your Wallet can accept payment from this Wallet).
Don't be foolish, no one is selling wallet files that have any value. Just go to the technical support boards and count how many newbies show up asking how to brute force wallet.dat files they "found on an old hard drive." All of these poor souls were scammed.
I don't know why I'm trying to save an obvious scammer from being scammed, but that's just how I roll.
What is that website called?
The website is called theoldestscaminthebook.com.
