Send a quick quote by text that won't come back to bite you

Help me send a quick quote by text or WhatsApp that's clear and protects me.

What they asked: [paste their message]
What I can tell from it: [e.g. photos show a small leak under the sink]
My price or range: [amount]
What's included: [e.g. labour and standard parts]
What could change the price: [e.g. if the pipe is corroded, access problems]
How long the price holds: [e.g. 14 days]
Next step I want: [e.g. book a visit, confirm a date]

Ask me 1 or 2 questions only if something essential is missing.

Then write:
1. A short quote message, under 80 words, with the price, what's included, what's assumed and the next step.
2. A one-line version for when they just want a number.
3. A friendly follow-up if they don't reply in 3 days.

Friendly and clear, UK English.
