Production Scheduling Spreadsheet Consultation

I need an expert to help me improve my existing spreadsheet for scheduling and managing production based on inventory. The ideal freelancer should have extensive experience in spreadsheet consulting and can provide insights on how to better track comprehensive elements like resource allocation and budgets.

Key Requirements:
- Expertise in spreadsheet consulting, particularly in production management
- Ability to provide advice on improving usability and functionality of an existing spreadsheet
- Experience in helping to design comprehensive project tracking spreadsheets

I already have a spreadsheet, but would like advice on improving its usability and functionality.

Please use Google Sheets for the spreadsheet improvement.
