Locating a company able to supply quality custom made cabinets is no easy task. Similarly to many products wood cabinets are mostly offered in standard models to fit everyone's needs. And then when you think you have found someone willing to manufacture your custom designed cabinet they know require a high minimum of pieces to be made at once! The whole process of manufacturing one to a few custom cabinets is unexpectedly time consuming. The manufacturer first has to study the custom cabinet design, clear any questions and misunderstanding and then figure a way to produce the custom cabinet inexpensively. Since this may require a few tries some manufacturers will stay away from the single custom cabinet type of production. I would suggest trying to locate a long established glass display showcases and cabinets company. Explain your custom cabinet project in details and just give them ample time to come through.
