1-What you need to get through the door of your investors is an 'Elevator Pitch'
It will be an 50-60 words short and concise brief of your business
2-Next will come a page long draft of your Business plan
3- after the first two steps, when you get a sit down with the investors will be an in depth analysis of you Business plan which will include the following points:
Financials, Cash flow management, how fast do you plan to upscale the business, return on investment for the Financing company, typically they will look for returns 50-60 annually for high risk businesses and 30-35% from moderate risk businesses
