To be a successful entrepreneur, you should have good ideas, but the definition of a good idea varies depending on whom you ask. A great idea should have several features. For example, good ideas should be novel and unique, which means no one has thought about it before. Also, good ideas should be productive, and it is essential for the ideas to be transformative. Offer a soup-to-nuts business plan, including market research, the business plan narrative and the financial statements. Plan your fee around the main one that the client will want and offer the others as add-on services. You can give clients an electronic file and allow them to take it from there, or you can keep the business plan on file and offer the service of tweaking it whenever necessary. Have business plan samples to show clients--and make sure to include your own!
