You are not going to get a pre-existing good business for $150,000
Any business is only worth its accounts and how much net profit it makes. a business that nets about $30,000 a year is maybe worth $150,000 which is not alot of money to make and live on. At 5 times P/E for $100,000 income you would need to spend $500,000 for a business.
that is alot of money to obtain, too much for most people
