Qualify an inbound lead in five questions

Someone just contacted me about working together. Help me decide if they are a good fit before I spend time on a call.

What they sent:
"""
{{inquiry}}
"""

My ideal customer: {{ideal_customer}}

Give me:
1. **Five qualifying questions** to ask them, in plain language.
2. **Green flags and red flags** to watch for in their answers.
3. **A short, polite reply** that asks the top two questions and proposes a next step.
