Toilets, Sinks, Showers, Tubs and Disposals - Kitchen Sink Re-Porcelain - Not Re-Glaze

We have a large iron sink that we want to reporcelain. This is not reglazing -like the Miracle Method or others - this is actually sandblasting off the old porcelain and reporcelaining a sink including heating the thing up to 1400°F in a huge oven. We have already been in contact with a place near St. Louis that does this, but are thinking that there must be some place closer. We live in New England and have relatively easy access to to both the Boston and New York City metro areas. Does anyone know of a place that reporcelains in these areas?

Thank You,

Steve

The only way I would think to find out about someplace local would be to do a gooooooooooooooogle search for keywords and states to see if this produces any results.
