1. Btcrecover (https://github.com/gurnec/btcrecover). You can start by reading the tutorial (https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md).
2. WalletRecoveryServices (https://walletrecoveryservices.com/). You will have to pay up to 20% fee If they manage to crack it.

It is best to check coins in that file before wasting your time discovering the password.
Also instead of giving the entire wallet data to a third party, I suggest you use ---->https://github.com/gurnec/btcrecover/blob/master/docs/Extract_Scripts.md  (test password without having full access)

How old are we talking? I own what I believe is the most powerful password cracking cluster for pre v2.8 electrum wallets.
