The U.S. Small Business Administration is a wonderful resource. Yes, it can be fairly bureaucratic at times, depending on what you want to do. And yes, some parts (especially some of their loan programs) are better for smaller, growing businesses rather that brand new start-ups. However, if you take a look at their website, there are many resources there for the taking.
One of the tools offered is a self assessment of 'are you ready to start a business?' This is ideal for those 'wanna-be entrepreneurs.' What I like about the assessment is that based on the answers you provide, they offer suggestions for your next step in the entrepreneurial process and link you to helpful resources.
This is just a sampling of what is available on the SBA's website. In the coming months, I will periodically profile some of the other facets that I think you will find useful.
