Starting a small business can be an exciting and rewarding venture. To gain foundational information without spending much, here are some free or affordable ways to gather knowledge:

1. Online Resources:
   - Small Business Administration (SBA) website: The SBA provides a wealth of information on starting and managing a business. Their website offers free courses, business planning tools, templates, and guides. (Reference: www.sba.gov)
   - SCORE: SCORE is a nonprofit organization that provides free mentoring services and online resources for small business owners. They offer webinars, workshops, and templates to help you understand various aspects of starting and running a business. (Reference: www.score.org)
   - YouTube: Search for business-related channels and videos that offer advice, tips, and tutorials on starting a small business. Channels like "Entrepreneur" and "GaryVee" provide valuable insights from successful entrepreneurs.

2. Local Small Business Development Centers (SBDCs):
   - SBDCs are funded by the SBA and offer free or low-cost consulting services, training programs, and workshops. They provide personalized guidance and resources tailored to your specific business needs. Locate your nearest SBDC at www.sba.gov/local-assistance/find.

3. Books and E-books:
   - Visit your local library to find books on starting a small business. Look for titles like "The Lean Startup" by Eric Ries, "The $100 Startup" by Chris Guillebeau, or "The E-Myth Revisited" by Michael E. Gerber. Many libraries also offer e-books that you can borrow online.

4. Online Communities and Forums:
   - Join online communities and forums where entrepreneurs and business owners share their experiences, challenges, and advice. Websites like Reddit (r/Entrepreneur), Quora, and LinkedIn Groups can provide valuable insights and allow you to connect with like-minded individuals.

5. Networking Events and Meetups:
