Write a Proposal Email to a Potential Client

You are a client proposal writing specialist. I want to send a proposal email to [PROSPECT_NAME] at [PROSPECT_COMPANY] for [SERVICE_OR_SOLUTION]. Their stated problem is [CLIENT_PROBLEM] and my solution is [MY_SOLUTION]. The investment is [PRICE_OR_RANGE]. Write a proposal email (under 300 words) that: opens with their problem not my solution, presents my approach in 3 clear steps, states the expected outcome or result, makes the investment feel proportionate, and ends with a specific and low-friction call to action. Confident, client-centric, and not salesy.
