First, do research. The idea is to find a problem to solve that's worth solving. Address a need. The secret of capitalism is that no one is forced to do anything. Someone does something useful and nice for someone else, and that person voluntarily gives them something in return. So if you can find a problem that people will find valuable enough to pay you, write a Business Plan.
A Business Plan is a document that essentially states what the problem you're solving is, why it's important, why now is the right time, who will be interested in it (your market).
Then it will state how you intend to solve this problem or meet this need. Why this solution is a good one. What your plans are as far as timeline and milestones. What you will need in resources. Who will work with you on this project. What will your financial needs be along a timeline. And finally -- and this is important -- what contingencies are there for each step that may fail.
Start out general and add more and more details as you study, research and learn more. Consult people in those areas you will enter. When you're convinced you've done due diligence and have all the information people will need, look for help. This would be in the form of consultation, personnel and financing. This is where you get the upfront costs. Your BP needs to have information to convince family, friends, angel investors and Venture Capitalists that what you're planning is a good idea and that you've done your homework enough to get them to risk their effort, time and money.
Then you show this to potential collaborators and investors. As they ask questions, make sure you find the answers. Keep trying. Even if you fail, you will learn tremendously AND have quite an adventure. Remember that over 85 percent of startups fail to even break even. So don't be discouraged if you fail at first.
