Recently I provided links to state resources for all residents. These resources can help anyone perform research on any topic, but of course they can be especially helpful for researching business topics.
The following post will help identify resources for researching starting a small business in each of the 50 states. The first place to start might be the U.S. Small Business Administration's district offices. The federal Department of Housing and Urban Development Small & Disadvantaged Business Utilization Program has state level resources. Another resource for many states are LinkedIn groups and Facebook groups of entrepreneurs and small business persons. Lastly, but certainly not least don't forget to check with the local Chamber of Commerce for the area in which you plan to operate your business.
