. After looking around, I learned – It depends on what type of business you want to open. If it is a small business, then you could work a job while you start your business using funds earned from your employer. You must make your five-year plan to ensure that at the end of five years would still be in business. You will not know the amount of money you need until you make your business plan. This plan contains a list of your expenses (all inclusive) and the costs of making and selling your product, etc. If your business is small and sole proprietor, you could start by doing work "type of service" itself as capping, cleaning gutters, cleaning garages, noting a greater or grocery shopping for others around person for a fee. Good luck to you.
