I'm actually going through our local Chamber of Commerce "Fast-track" course right now (sponsored by the SBA).
Since I have many years of experience in business (mostly in South America do doesn't count in their minds here ;) and in dealing with budgeting, premises, etc... I thought that this course would be boring and not provide much of a benefit to me.
Well, the class is definitely NOT boring, though it still hasn't really presented much new information to me. HOWEVER!!!!! This class has given me a much better understanding of organizing the information I have, and given some excellent sources for both networking and for finding lower cost solutions.
I would check with your local Chamber of Commerce and/or the SBA (http://www.sba.gov).
Best of luck to you, and... if you have a good idea, do some good research, and make yourself a good plan (and follow it), then you have significantly increased the chances of your company being a success.
