Hi mate,
Very sorry to hear about your lost coins.
You're getting some great advice in this thread, and it seems like some smart folks are already helping out.
I'd also be willing to give this a shot. I work in security and cracking passwords is part of my job. I've developed my own tricks, and perhaps one of them will work where the others have not.
I'm new on here, but you can see some of my posts on reddit at
http://reddit.com/u/initstring.
I'd only need a hash of your wallet file to work on the password, not the wallet itself. I would ask for a fee if I could recover it.
Let me know if you're interested. If not, keep working hard and following the good advice on this forum.
Either way, best of luck and I hope you get your coins back!
