While writing a business plan necessitates the inclusion of facts, figures, numbers, graphs, financials, etc., the narrative surrounding the why of your proposal is what will likely draw people into helping you achieve your vision. Do you sound passionate about your product? Do you sound knowledgeable? Does it sound like you have what it takes to not only start your business but develop it and work through anticipated and unseen challenges? No? Does it sound like you relied on a sample plan instead? Well it may be a good idea to check out some of the writing seminars available for assistance with writing your plan. Many of these seminars do cost some money, although others can be attended for a very nominal fee. Courses like these can help you find your "voice" and deliver a more compelling proposal.
The internet is a fantastic resource for writing a business plan, but for some people, nothing beats a good old-fashioned book. Your local library has entire sections dedicated to the multiple aspects of business development, and you can be sure to find several books about how to write a business plan. Best of all - these are free! If your local branch does not have the book you're looking for, check the catalog and request a book transfer. Sometimes, the perfect books about writing an effective business plan or ideas for a sample business plan are just an inter-library loan away.
