That is a great thing to make sure you have in your business plan, that your business will be built around those real customer wants. Do not make callous assumptions, or statements like "I know what people want", "People are going to love this", and so on. Have you done your research? Do you really know that the people you will be targeting want your product / service, and crucially do they want it AT THE PRICE that you will be offering it at? Whilst confidence in your plan is fantastic, you must make sure that it does not lead you down a blind alley along a path that is not desired by your target market. Don't assume what customers want, do your research and make sure that is clear from the start in your business plan.
Then the question is; is your market going to be big enough to provide you with 12꽭 leads for the next year and how many will you need each of the following years? It may be easier than you think to figure this out. You would do some research and with the aid of the U.S. Census Bureau you can roughly determine whether your plan can be supported by your market or not. So what do you think? Is it better to build a business plan around what you want in life then see how your business can maybe give you that or is it better to use a sample business plan for a small business where you are probably guessing?
