I'll do this service for anyone, for 2.5 BTC (while 1 BTC is in the $20 range), including shipping. If you receive the package un-tampered, you should be safe. Contact me if you are interested.
I am not questioning your integrity personally, but if someone were to take you up on your offer, it automatically makes what you are selling completely worthless (ie. complete wallet security.) That person could never be secure and with certain knowledge that another copy of his wallet is not out there in the ether somewhere..."trust" should never be a lynch-pin of ANY security system (at least it need not be.)
I like the method though.
