Bankruptcy!!! Wow, that certainly is a size 14 'other' shoe hitting the floor!
was your judgment or debt dismissed in the bankruptcy?? If yes, it is DOA.
If not, what are the dates of filing, discharge, debt and judgment??
Also:
1) The fact that he says 'construction' and 'self-employed' is pretty innocuous. In itself it does NOT mean he owns a construction company, he could just be a contract ditch-digger.
2) You say he 'owns' several corporations. An individual cannot own a corporation (I know, semantics, but it is important to understand the relationship, or lack of). A corporation is owned by shareholders. He may be a majority shareholder, but he is not the 'owner'. And unless your judgment includes the corporation as a debtor, the corporate assets are immune from seizure.
3) An alternative to an Informational Subpoena is a "Post-Judgment Order for Discovery". This requires the judgment debtor to appear at a certain time and place and to answer questions, under oath, about his income and assets. The questions are asked by the attorney for the judgment creditor. The judgment debtor may be ordered to produce certain documents at the time and place of the appearance. If the judgment debtor fails to appear and/or to produce the required documents, further Court proceedings are available which can eventually lead to the arrest of the judgment debtor"

4) Your post said, "I asked the court for a contempt hearing against him but they have not been helpful. The judge said I had to talk to the court about other requirements I must meet before he will have a contempt hearing."
What did the court say when you talked with them?? What other 'requirements' must be met??
Finally, here is a link to a good format for an "Informational Subpoena" for New Jersey:
