Budget Policy Draft & Model

I need help turning my budgeting principles into a clear, actionable financial policy, complete with an accompanying workload plan and an Excel-based model that shows how the policy plays out under different scenarios. The finished package must let decision-makers see, at a glance, how funding requests flow through the process, who signs off at each stage, and what workload each team can expect as volumes rise or fall.

Here is what I am after:
• A concise written budgeting policy that sets approval limits, timing, escalation paths, and reporting standards.
• A workload plan that translates the policy into roles, tasks, and weekly effort estimates, so I can staff appropriately.
• A dynamic financial model (Excel or Google Sheets) with clearly labelled inputs, assumptions, and dashboard-style outputs for stress testing the policy.

Accuracy and clarity are crucial, so please base the model on generally accepted public-sector budgeting practices but keep the structure flexible enough for future amendments. I will share my current draft notes and staffing data as soon as we start. Because this is time-sensitive, I’d like an initial outline within 48 hours and a polished, review-ready set of deliverables shortly after. Let me know your relevant experience and which modelling tools you prefer so we can move fast.
