collect on a judgement

I am looking for someone to help me collect on a judgement of approximately $6000. The debtor is a lawyer who lost his license to practice. I have his last known office address but I’m not sure what collection method to use, so I’m seeking assistance from a professional. I am looking for professional, reliable services and am hoping to find someone experienced in this kind of work to get the best results. If you think you have the skills and resources to help me, please reach out. Thank you for your consideration.
