Hiring/training it's a time consuming process, especially for large scale project like this (think, 67k towers across entire united states). Usually telecoms RFI pretty much entire project from third party vendors (or few of them, on order to reduce risks), with very long list of requirements covering everything from software integration to hardware deployment. Vendors will bring teams of their own engineers for "higher level jobs" and a whole bunch of "licenses" subcontractors to do actual track rolls. In case it's a complicated project, like upgrade to 5G, vendor most likely can't provide entire solution by itself, so it will be a "consortium" of vendors that stich up complete solution that is organized by vendor that answers RFI. In this case each vendor may have it's own subcontractors who may have their own subcontractors etc...
