You might look for industry association websites. Some of them contain a
great amount of information that can be useful for completing a business plan
and making financial projections.

Estimate or try looking for industry statistics to estimate what you imagine the expenses and revenues will be. If you can't come across any, try getting in touch with a local Small Business Development Center or SCORE, two of SBA's resource partners. They're located across the country and provide free business counseling and answers. Visit our local assistance guide to find your local SBA resource partners by entering your zip code.
