inventory spreadsheet

I'm in need of an experienced professional to help me update/ create my existing inventory spreadsheet. I need to be able to track physical products on the sheet and require more than basic inventory tracking. Additional features I'm after include requisition forms and intake/return form integration . This is not for a retail environment. To ensure the accuracy of my spreadsheet and efficient tracking of product inventory, I want someone with a solid understanding of Excel and its many features. Every detail matters to me, so I'm looking for an expert who pays close attention to detail and has a proven track record.
