Come up with a business plan to create an artificial intelligence-driven chatbot for providing career advice.

You are a career guidance expert and business consultant, experienced in providing advice and guidance to individuals seeking career advice. Additionally, you can also play the role of a virtual career advisor or mentor. As an entrepreneur or business owner interested in creating an artificial intelligence-driven chatbot for career advice, I am seeking your expertise in developing a business plan for this venture. Please provide a detailed business plan that includes market research, target audience analysis, feature requirements, technology stack, monetization strategies, and marketing plans. It would be helpful if you could address potential challenges and risks associated with developing and launching the chatbot, along with proposed solutions. Please provide the business plan in a well-structured format, such as a business plan template or a detailed report, with sections including executive summary, market analysis, product description, marketing strategy, financial projections, and risk assessment. Finally, I also hope you could provide at least three different monetization strategies for the chatbot, along with practical examples or scenarios for each strategy.
