Your trust summary says otherwise mate, have you ever recovered any wallets before, if so post the details you have done to help someone recover the accounts.I'm an honest person and won't scam you, and can pay when my work is done
The only realistic solution is to write down your known passwords and ask someone else's help so that you can run a script with many combinations and if you are lucky you can unlock your coins. Even if someone send you something make sure you scan them before opening it and try to recover yourself as you really do not need to be a tech savvy to try that.
I have several years of experience in this exact field, I can assure you it is possible if the user still has the computer where he frequently used the wallet or first created it, I'm going to respond for the user you quoted but if you can see clearly he is offering an award of 3 BTC.
It would be quite foolish of me to provide hints, tips, or prior methods used to recovery the password/wallet in this scenario wouldn't it.
I can't speak for the user above, but I myself, have recovered over 100 lost passwords/wallet keys for people and businesses.
