Reassure a nervous first-time customer

Help me reassure a nervous first-time customer.

My service: [what you do]
What they've said: [paste their message if you have one]
What first-timers usually worry about: [list]
What actually happens on the first visit: [step by step]
What they should bring or do beforehand: [list]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. A warm reply to their message.
2. A "what to expect" note: arriving, the first 10 minutes, how long it takes, what happens after.
3. Answers to the 5 worries most likely on their mind.
4. A short day-before reminder that makes it easy to ask a last question.

Use only what I've given you, leave blanks for any price or fact I haven't given, and don't invent anything. UK English, calm and friendly, no medical claims.
