Starting a new business is a multi-step process, and there are many things that have to be considered. Not only do you need to register your business, obtain licenses and insurance, file tax forms and deal with your local and state governments, you also need to appoint officers, form a board of directors and possibly seek out business advisors.
Business advisors differ from a board of directors because they are less formal and can be easily changed depending on your needs. Additionally, advisors are not required to hold meetings, and are only expected to devote a few hours each year (i.e. anywhere from 20 to 40 hours) advising you on your business.
