How to write a freelance proposal that makes the next decision easy

Editorial follow-up: compare options by scope
For a hypothetical catalogue project, one option could update ten existing descriptions; another could update ten descriptions and create a reusable style guide. Both should meet the same stated standard for accuracy.

Explain the extra deliverable and the additional time it needs. Do not make the lower option deliberately vague or imply that basic accuracy costs extra. A buyer should choose based on useful work, not uncertainty about what the cheapest option omits.
