If he owes you enought to make it worth your time, have your lawyer write a letter to him sent certified mail with return receipt. If he understands that you take your work seriously and expect to get paid, he may reconsider.
I've only had to take 2 people to small claims court in 30 years of business. Both were for small amounts of money, but it was the principal of the thing. I won both cases. One claim was only for $80 worth of artwork plus interest and court costs. Ended up collecting $235. The other was a realtor (President of his local Board of Realtors for heaven's sake!) who owed me abut $200 for an order (rush of course) of 500 imprinted balloons! I won the case in court, but he still refused to pay, so I filed a lien against his business.
