The easiest place to start is with any competitors currently in the space you are interested in. If they are publicly traded, their financial statements are a treasure trove of information regarding the market.

Even private companies reveal a lot when a Googled, although sometimes its a matter of putting together the puzzle pieces to see the big picture.

Trade associations can also be very helpful. Sometimes these reports can be expensive, but most of the time they are free.

Yet another option is to talk to the people you think would be customers. Learn everything you can to develop a better understanding of the demographic and let that specific criteria guide you.
