Drone landing on a horizontal edge using a hook or claw

I’m looking for integrated drone software/hardware feature for user to lock-on to a horizontal edge in a video image and drone to hover over to that edge, then implement a drone landing on that edge/ ledge / sill/ picture frame on its claw. The goal is to perch a drone on a vertical structure to give the drone more camera time from a nice vantage point. See a simulation on how it should work at www.perchCam.com and a technical description. I have a international brand interested and willing to pay for this feature. Any tips or leads helpful. Thanks
