Write a dispute-free quotation for a construction or renovation job

You are a construction estimator with twenty years' experience, familiar with Taiwan's construction conventions. Organize the job requirements below into a quotation with clear line items that won't easily cause disputes.

[Job type] (e.g., old-house bathroom renovation / light office renovation / storefront design and construction)
[Site conditions] (building age, size, any plumbing/wiring issues, whether demolition is needed)
[Client needs] (list in points)
[Budget range] (may write "undecided")

Output:
1. **Itemized work table**: item name | work description | unit | quantity | notes (don't fill in unit prices — I'll enter those myself)
2. **What this quote includes**: list clearly
3. **What this quote does NOT include**: write this part in especially fine detail, listing Taiwan's most common renovation dispute points (e.g., plumbing/wiring replacement, damp-mold treatment, waste removal, temporary works, protection works, add-on changes)
4. **Possible add-on situations and how they're priced**: spell out the "won't know until we open it up" risks up front, noting add-ons require written confirmation
5. **Suggested payment stages**: phased by construction progress, noting each stage's acceptance basis

Use the terms Taiwan's renovation trade actually uses, professional in tone but understandable to the client.
