Write a service page

I work in marketing at a law firm. Help me write a web page for one of our services.

Context: People compare three or four firms in one sitting. They look for who will handle their matter, how long it takes and what it costs.

Before you start, ask me for anything missing from this list:
- The service and who it is for
- What happens, step by step
- How we charge
- What we cannot promise

Then:
1. Open with who this is for and the problem it solves.
2. Explain what happens in order, in plain words.
3. Explain cost or how pricing works.
4. Answer the five questions people ask before getting in touch.

Give me:
- A headline and a one-line summary
- The page, 400 to 600 words, with question headings
- One call to action

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 legal information only. Never write anything that reads as advice on a person's own situation, and never suggest an outcome is likely or guaranteed.
- 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 the partner who approves marketing should see:
- Price and timescale information your regulator expects on this type of page
- Words like specialist, expert or leading, and the basis for them
- Who is named as doing the work and their status
