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.
Finally, it's important to consider that when you're writing a business plan, you don't want to cut corners or rely on a sample plan from a book or website. The business plan is a representation of your professionalism and your desire to succeed, and the quality of your content should reflect this. So while tips and tricks are good for making the most out of your time and resources, it's never a good idea to gloss over important aspects of your plan - namely, the quality of your writing.
