Thanks for your input. I did send an invoice four years ago, but he ignored it. Another complicating factor is that the project (and company) is long dead.

My next step, as many have suggested as well, is likely to consult a professional of specialized letter writers.

Definitely. I have been doing this ever since.

Resend a demand for payment. The possible answers include "A check." and "A universe of other responses, any of which you can get checked by a letter-writer." For example, "X Corp owes you money. I don't." is entirely possible. It is an incredible step forward over where you are today.
