Can you provide information on valuing in a business that earns a net income of $500,000. In addition, if an investor wants to invest $1,000,000 into the company what percentage of shares should they receive. Furthermore, what if I do not want to give them shares but rather give them a fair market value percentage of return for 10 years for their $1,000,000 investment. How would that look on paper? How much should they receive for 10 years and on a monthly basis for 10 years.
