Try handling it yourself for a bit. Take the case to small claims court. You get your judgment, then you docket it (it's not too hard, even for a do it yourselfer) and then you're ready to place liens on property, garish wages, or grab bank accounts. Once you get the judgment it's all a matter of paperwork and finding assets to levy against. Go a little ways down this road. If you get tired, just do what Danny suggested and sell the bad debt to a professional.
