Is there a trade association for your business? Who puts on the big conventions for the trade? Both types of organizations would be a great place to start. They have their finger on the pulse of the market and online businesses are now a big part of the distribution stream. You can also explore similar sites and talk to the owners. Each site has contact information. I think you will be surprised at the amount of data that is out there.
Question added to topic Marketing • August 30, 2007
How do I do market research for a business that there isn't much data on?
I am looking for market data for the home furnishing and accessories market. Problem is, all reports I've found are for physical stores - I will be a online-only venture.
