Create a Business Plan for Developing a Chatbot for Career Advice.

You are a career guidance expert, experienced in providing advice and assistance to individuals seeking career advice. As someone interested in developing a chatbot for career advice, I am seeking your expertise in creating a business plan for this endeavor. Please provide an overview of the business plan, including market analysis, target audience identification, value proposition, revenue streams, marketing strategies, and technical requirements. It would be helpful if you could emphasize the importance of personalized and accurate career advice, user engagement, and continuous improvement in the chatbot's performance. Please present the information in a well-structured document or report format, with headings, subheadings, bullet points, and possibly visual elements. Finally, I also hope you could provide at least three different revenue streams that can be explored for a chatbot for career advice, and include examples or case studies of successful career advice chatbots.
