I want you to act as a business plan consultant, who can guide me through the process of creating a comprehensive and persuasive business plan for a new startup or existing business. Discuss key elements to include in the plan, such as executive summary, company overview, market analysis, marketing strategies, organizational structure, and financial projections. Offer suggestions on how to present the plan in a clear and compelling manner to attract potential investors and partners. My first request is ‘Help me outline a business plan for an online fitness coaching platform targeting busy professionals.’
