Spend less time on the unpaid half of freelancing

A client has described the job in a WhatsApp voice note or three scattered messages.

You are helping a freelance {discipline} in India write a project proposal.

Here is everything the client has told me, exactly as they said it:
"""
{paste the messages}
"""

Write a proposal with these sections and nothing else:
1. What you asked for — restate their goal in plain language, in their words where possible, so they can check I understood.
2. What I will deliver — a numbered list of concrete artefacts, each one a thing they can open or use. No verbs like "support" or "assist".
3. What I need from you — the specific inputs, access, and decisions I need, each with the point in the project where it becomes blocking.
4. Timeline — working days, not calendar dates, with a named dependency for each stage.
5. Price and terms — leave the number as {AMOUNT}, state 50% advance, and note that anything outside section 2 is quoted separately.

Rules: no adjectives about my skills, no mission statement, no mention of AI. If their brief is missing something you need for section 2, do not invent it — list it under "Questions before I can quote".

The proposal went out and nothing came back.

I sent this proposal {number} days ago and have heard nothing:
"""
{paste the proposal summary}
"""

Write a follow-up under 80 words that: does not ask "just checking in", gives them a reason to reply that is about them and not my anxiety, adds one genuinely useful thing (a relevant observation, a link, a small piece of thinking about their problem), and makes it easy to say no or not now. One question at the end, answerable in four words.

Due date passed. You need all four messages now, not one at a time.

Invoice: ₹{amount}, due {date}, now {number} days overdue. Client: {new / long-standing}.

Write four reminders, each with the day it goes out:
1. Two days after due — assume it was an oversight. Friendly, one line, re-attach.
2. Seven days — slightly firmer, restate the amount and due date as facts, ask for a payment date.
3. Fourteen days — name the delay plainly, state any late fee in the terms, ask who in their accounts team I should speak to directly.
4. Twenty-one days — professional, unemotional, states what happens next and gives a final date.

Each under 90 words. None sarcastic, none pleading, none threatening. Every one sendable to a client I would still like to work with.
