How do I get an AT&T cell phone tower?

Excuse me, but I'm curious about something. How does one go about acquiring an AT&T cell phone tower? Is it something that's available for purchase directly from AT&T, or do I need to go through a third-party provider? And if so, what kind of qualifications or requirements would I need to meet in order to be considered a viable candidate for owning and operating one of these towers? I'm genuinely interested in learning more about the process and any potential challenges that might arise.
