1. Get a job in the business. Learn all you can. Pay special attention to tax laws, federal, local and state. Learn all the licensing requirements.
2. Take some small business classes through a local college or trade school.
3. When you have done the above, you might be ready.
4. There is no way anyone can teach you to run you business through an online forum. 50% of all business start ups fail in 2 years, 90% fail in 5 years. Without the necessary knowledge, you are doomed to fail.
