I need a clear, persuasive penawaran jasa that positions my company as a reliable partner for Pengembangan. The document will be sent to prospective Indonesian clients, so it must read naturally in Bahasa Indonesia, use proper business etiquette, and outline how our end-to-end development expertise solves their pain points. Scope • One formal proposal letter (1–2 pages, .docx + PDF) ready for client distribution. • Content must include an opening greeting, concise introduction of our team, overview of our development capabilities, highlights of past successes (you can leave placeholders for exact figures), timeline and workflow summary, plus a polite call-to-action. Acceptance criteria • Written in fluent, professional Indonesian. • Tone: friendly yet authoritative, focusing on service value rather than technical jargon. • Structure follows standard Indonesian business-letter conventions. • Delivered within two days once we agree on key company details (I will supply logo, contact info, and project examples). If you’ve drafted similar tech-service proposals before, please share a brief sample or outline your approach so I can gauge fit.
