if your question is where to find farmhouse sinks, it depends if you are looking for old or new. Old ones might be found at flea markets, architectural salvage businesses, antique dealers that specialize in large farm stuff. New ones are very popular right now, at least the farmhouse style sink, one large sink with no center divide. These can be seen at all the large home stores, Home Depot. Lowes. Menards. There are also many businesses that sell nothing but kitchen and bathroom sinks. Look in phone book or on line under kitchen remodelers. They will want to know the dimensions of what you are looking for, and will probably want them in inches, not metric.
