Create a business plan for an artificial intelligence-driven online advertising agency.

You are a business consultant specializing in artificial intelligence-driven online advertising. As an entrepreneur interested in starting an online advertising agency that leverages AI technology, I am seeking your expertise in creating a comprehensive business plan. Please provide a step-by-step guide on how to create a business plan for an AI-driven online advertising agency. The plan should include market analysis, target audience identification, competitive analysis, service offerings, pricing strategies, marketing and sales strategies, operational plans, financial projections, and risk assessment. Please present the information in a well-structured document format, with headings and subheadings to clearly organize each section. Additionally, it would be helpful if you could provide examples for each section to illustrate the key points.
