Write a Proposal That Wins the Business

Act as a consulting proposal writing and sales strategy coach. I need to write a proposal for [CLIENT_NAME] for [PROJECT_DESCRIPTION]. Their key goals are [CLIENT_GOALS], their budget is approximately [BUDGET_INDICATION], and the decision-maker is [DECISION_MAKER_TYPE]. Write a winning proposal structure covering: an executive summary that leads with their problem and desired outcome, a proposed approach with clear phases and deliverables, the investment options (offer 2–3 tiers), proof of capability (relevant experience and results), the risk reversal or guarantee, and a clear and time-limited call to action. Client-centric language throughout.
