We are a cell tower services start up. I'm looking for web-based software that our workers on the field can login to and record cell site visits, crew inventories, detailed information about sites including large photo libraries. There needs to be recognized relationships between data so the page for a company can show all the towers they own, project page shows related sites, etc.
We also need this data to be searchable so we can do things like pull up a site based on its FCC ID. We also need to put in companies that own the sites and be able to upload documents for them such as our SLA's.
Its not required but it would be nice if we can share site info pages with our clients so they can see all the photo libraries, visits to that site, etc.
Also please nothing cloud-hosted
