I am interested in starting a home-based business. However, the
opportunity in question is somewhat unique. Here is a link:
http://wealthtimesten.com/BH1688/. Basically, my question is since the
business can virtually run itself (literally), with no real effort
required by the user (except for the one-time investment), does such
an opportunity require a business license? I live in Cypress,
California. Thanks.

Practices vary: There is a good chance you can skip the bussiness
licence etc, until and if, you have a large volume of bussiness.
Ventures that require little effort on your part are often scams
and/or illegal.   Neil
