Broker
He is simply a broker. There are good reasons to use a broker who has been around awhile and understands the business rather than dealing directly with the end party whom you have no reason to trust. A broker always gets commission for his services either by charging a fee or pressing the supplier for the discount he knows he can get, and often both! As for cracking RSA-1024, the only practical way of doing this is to "obtain" a copy of the private key.
