Write a landing page for an ad

I work in marketing at an insurance broker. Help me write the landing page an ad sends people to.

Context: Someone who clicked an ad wants to confirm the broker covers their trade, roughly what it costs and how to get a quote today.

Before you start, ask me for anything missing from this list:
- The ad
- The offer
- The form or booking step
- Proof we can show

Then:
1. Repeat the ad's promise in the headline.
2. Remove every link that is not the one action.
3. Answer the three doubts that stop people.

Give me:
- Headline
- Page copy under 300 words
- Form fields to keep and to cut

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Give general information about insurance only. Never say that a particular person or business is covered, never suggest a claim will be paid, and never call a price the cheapest or the best.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else our compliance officer or whoever approves financial promotions should see:
- Cover summaries, with significant exclusions and limits shown as compliance expects
- The basis for any price, 'from' figure or saving
- Regulatory status and insurer details in the footer
