Filemaker App

I need a filemaker app developed that can take specific assets specified by model 3 and serial number. From the app I would be able take a customer request create a work order that the assets inventory can be allocated to by barcode scanning from the ipad camera. then it would be sent to a fulfillment specialist and the asset delivered. It would show where it was to be delivered by map as well. I want to deploy this on a hosted server for several people to have use of the app either via PC, Mac or IOS device or tablet as it would be server hosted. I am attaching a vision spec I presented to a custom developer.
