One of the best places to look for business help is the nearest Small Business Development Center (SBDC). There are more than a thousand SBDCs across the United States. They're associated with the U.S. Small Business Administration, and typically sponsored by government and education organizations, such as a college or university. The cost for SBDC assistance will range from free to very reasonable. Go to www.asbdc-us.org to find an office near you.
Also visit the SBA Business Information Centers (BIC) and the Service Corps of Retired Executives (SCORE) training programs. These generally are excellent and economical sources of business expertise.
Beyond that, consider your local university or community college. Think about what help your vendors can offer. And ask your banker, attorney and accountant for recommendations. You might also find a business consultant in your area who can help.
