Another option you'd have is to try and get some professional help recovering your wallet. I've heard good things about Wallet Recovery Services, and from reading through their site a bit, it looks like there might be a possibility of cracking your wallet password, since you know what the pattern of the password was like. Obviously since it was a very complex password, there's a slim chance that they'll be able to recover it, but I suspect they'd have more experience with recovering wallets than you would.

If you're not interested in that, then I'd say to give up on trying to brute-force your password. With a password that's 30 characters or more, with uppercase/lowercase/numbers/characters, you won't be cracking it anytime soon. You'd probably have better luck trying to find the original paper with your password on it.
