I might need to start a new thread in that case if I do.. sorry my friends! I saw this post and am in a similar situation and I am trying every option exhaustingly as I have a similar (more) balance.. with a corrupt wallet from 2012... I too offer a reward for successful results, I am of course trying to learn everything on my own and am not trying to send my wallet (obviously) which makes things as tough as can be of course, anyway i wanted to quote the post concerning the link that took me to (https://github.com/bitcoin/bitcoin/blob/48b5b84ee511d5ccd0d47bb0018c1b3c9ddebeff/src/wallet/walletdb.cpp)
which is the src/wallet/walletdb.cpp source code.. I have that same type of file (a little different/but same just older) and have been reading about going through the source code to retrieve the "redeem script" or the "derivation method" but first I wanted to ask .. what is that src/wallet/walletdb.cpp specifically? as I don't see any strings but I do see key all over.. and I also read the db can leave bits of unencrypted private keys in the db slack space, I just don't follow direction too well but I will try to follow the mentioned directions to get my wallet back, also wanted to ask (off subject mind racing) my python said "cannot import name 'generator_secp256k1' from 'pycoin.ecdsa" when trying to install bitwalletrecover. anyway hoping to get help with this as I have not asked for help on a forum before but been trying for years to figure it out, guess i finally reached my breaking point for my need to get help with this!!! thankyou for reading and I understand walletrecoveryservices is not trying to help me as I have already tried.. did I not save the right file? did I corrupt it and lose the info I need when I saved it possibly by saving it wrong?
  hoping I am not S.O.L!! thankyou for reading I appreciate all and any help, and as I said a successful return of my only hope in the world to not restart my broke ass from scratch will be compensated. CHEERS!
