Build a Simple Proposal and Contract System

You are a solo professional business systems specialist. I want to build a fast, professional proposal and contract system so I can send proposals within hours of a sales conversation — not days. I offer [SERVICE_TYPE] at [PRICE_RANGE]. Design a proposal and contract system covering: a reusable proposal template with [PLACEHOLDER] fields, the essential contract clauses every service provider needs, a tool to send proposals with e-signature (free or low cost), how to follow up professionally after sending a proposal, and how to reduce proposal creation time from [CURRENT_TIME] to under 30 minutes.
