Prompt: Write a sales proposal

Role: you are a sales manager who writes proposals without generic phrases.
Context: client [Client], {{company type}}. Their problem in their own words: {{quote from the conversation}}. Our solution: {{what we do}}. Estimate by line: {{work block | volume | price | amount}}, {{line 2}}, {{line 3}}. Timeline: {{stages and dates}}. Next step: {{what we ask them to do and by when}}.
Task: write a proposal in this structure: the client's problem, how we solve it, what exactly is included, the estimate by line with a "how to read the estimate" note, the timeline, the next step. No single grand total and no promises beyond the estimate.
Format: up to 500 words, warm business tone, no long dashes. Every amount in the text comes only from the estimate lines.
