Friendly AI for Casual Appointment Setting

I'm looking for a friendly AI to call my leads and set up appointments with a strategist. The AI should use a casual conversation style, making the calls feel less like a business interaction and more like a friendly chat.

Key Requirements:
- The AI should be able to collect preferred appointment times from the leads.
- The AI should be programmed to use a friendly tone throughout the call.
- The AI should follow a casual conversation script.

Ideal Skills:
- Experience with AI development and programming.
- Strong understanding of voice modulation and tone.
- Ability to create casual, engaging scripts for the AI.
