Hi Mike, very good for both clients and Realtors to get some good ideas on future re-models....thanks for sharing with us and I hope that your event is successful....
These home improvement fairs are also great places to bring real estate professionals together with buyers/sellers. If you've never tried one, it would probably be a good investment in time and expense.
These programs are very effective in getting attention to home improvement and real estate in general. Du Page County, IL has one every year at a local resort.
