How do you start a small ceramic business?

Your question is too vague so I'll ask lots more questions. What type of ceramics are you thinking of? Ceramics for electricity or functional ceramics for eating off of or perhaps decorative stuff? Do you use a potters wheel or hand build? Will you be using kilns to fire your product or perhaps firing in pits for that Old look? What cone will your ceramics be fired too and what type of clay will you use? Who are your customers? If this is a functional/decorative product, where will you sell your stuff - at a shop or at art shows? Full-time or hobby?
