Not sure if I correctly understood your need but seems like you lost/forgot the password of your bitcoin wallet.
If I'm correct about it I think you should try to contact this site
http://www.walletrecoveryservices.com/offering this service.
This is not my site by the way.
I just read of it here on bitcointalk in the past: this is their announcement thread
https://bitcointalk.org/index.php?topic=240779.0Dont know how much youy have in your wallet and how much you can trust their service because I don't have any direct experience.
hope this helps
