Business.gov - Official Business Link to the U.S. Government

Business.gov is "the official business link to the U.S. government."

Small business guides are arranged by topic, such as "Advertising and Marketing," "Business Law," "Taxes," and "Start and Manage a Business". Each guide provides a concise annotated list of links to relevant U.S. government information.

Under the tab "State & Local Info" there is a clickable map of the U.S. For each state there is a small business guide with links to local resources and answers to FAQ. The Florida Small Business Guide is available here -- at the far left is a link to the web sites for cities and counties in the state.
(This is a great resource for students working on local marketing projects....)
