Need advice from entrepreneurs and business owners

As the title say I need someone to guide me or mentor me I am 23 years old and currently pursuing a master's in AI. And I want to start my own business that is related to smart agriculture but I don't know anything about how to set up a business and I would really appreciate some guidance. Basically I need guidance with how to set up a supply chain like how do I find customers for my product and maintain that supply chain efficiently also no one in my family or extended family is a business owner that's why I am asking here for help.
