Have done something similar, couple of months ago, for road construction company with 16 external locations. Each location had items in storage and checked out items on construction site. Software was developed in Microsoft Dynamics NAV for its scalability, but I can easily put that logic in Access, for your convenience. I have even made some 3D images of tools and hardware for that project, I could do something similar for your app. Thank you for your time reading and considering my bid.
