You could also see if you can bend his ego into paying.

I had a simmilar client a while back. wrote e-mails send reminders and called every week. After a while I wrote a letter stating that i understand that he can not pay me so i offered to make a 10 payments contract to make it easier for him. That insulted him so much that he phoned me to tell me our bill was only very small and that we are a small compagny and he was an important developer bla bla bla. Got payed that same day. Ha
