Build a one-page sales page for one offer

Help me write a one-page sales page for a single offer.

The offer: [e.g. spring garden tidy, a 6-week beginners' course, a family photo session]
Who it's for: [describe them]
What's included: [list]
Price: [leave as a blank if you prefer]
How people book or buy: [e.g. booking link, phone, form]
Deadline or limit, if real: [e.g. 10 places, ends 30 April, or none]
What people usually ask or worry about: [e.g. is it suitable for beginners, what if it rains]
Proof I have: [reviews, numbers of customers, photos]

Ask me up to 4 short questions first if anything's missing. Wait for my answers.

Then write the page in this order:
1. Headline and one-line subheading that say who it's for and what they get.
2. Three short "this is for you if" points.
3. What's included, as a clear list.
4. How it works, in 3 steps.
5. Proof: where to place my reviews, using only ones I've given.
6. Answers to the common worries, as short questions and answers.
7. Price and the booking button text, with any real deadline.

Short sentences, no fake urgency, don't invent reviews or numbers. UK English.
