AI Sales-Lead Agent Setup -- 2

I need an end-to-end build of an AI agent focused on sales and lead generation. The goal is for the agent to attract, qualify, and nurture prospects automatically, then pass warm opportunities straight into my pipeline.

Here’s what I’m after:

• Configure the underlying model and conversation flow so the agent can greet visitors, ask qualifying questions, overcome basic objections, and capture key contact details.
• Automate follow-up sequences that score leads and route hot ones to me in real time.
• Set up integrations—email, my preferred CRM, and even social channels if that streamlines outreach—so the agent’s data lands exactly where I need it.
• Provide clear documentation and a quick demo call at hand-off so I can tweak prompts or workflows myself later.

I’m open to your choice of stack (Python, Node, low-code tools, webhooks, Zapier, etc.) as long as it stays maintainable and cost-effective. When you reply, please showcase similar automations you’ve shipped and outline the high-level steps you’d follow for this build.
