That view seems really cool @Oxkis
I have no specific template, but can subtract this as key items from our proposal:
- Short Intro
- Team About Section
- Problem Statement
- Solution and Proposal Overview
- The Project Goals
- Project Scope & Deliverables
- Budget Breakdown & Summary
- Notes & External References
Also, you can take a look to DeveloperDAO budget template or this BGD proposal as reference: https://governance.aave.com/t/aave-bored-ghosts-developing-bgd
