You can look into collection, but if you already were granted a judgment by the court, it is just a matter of attaching it to an asset.
Check with your court for filing the judgment. If you file/record the judgment, it will automatically wind up on their credit report.
Also, with judgment papers, your local sheriff's dept can help you garnish a salary of seize a bank account or other asset. Th LPA also has a new reporting feature at http://www.thelpa.com/lpa/credit-reporting.html
