I would recommend to follow these steps:
1 Select the industry you're interested in working in.
2 Research the kinds of businesses and various business models within that industry.
3 Perform market research to see where there is an unmet need -- geographically, pricewise, complementary products and services, etc.
4 Analyze the competition.
5 Develop a preliminary business plan for a business to meet that need.
6 Do some more market research to assess the realistic market potential for your business. Will people buy it?
7 Revise the business plan and determine your funding requirements.
8 If needed, seek out lenders or investors.
9Start the business.
Hope it helps you.
