This sounds more like a debt collection issue since it was delivered with an agreement for later payment. Small claims courts are full of this type of situation. You can call the courthouse and ask what the filing fee for small claims is. Used to be about $25 in my county. More than that now I imagine. Don't need a lawyer but he will be served by the process server. Might get his attention. A settlement in your favor will let you garnish his wages, BUT that takes a lawyer and might cost more than it is worth. Also make sure your story is straight because there is no paperwork for either side.
