Metal fence recommendations

Hello, I am looking to set up approx. 54 ft of a metal fence (at least 8 ft.) as my neighbor Airbnb’s and now I have people on my AC 🤔 They moved the trash can and jumped over my fence to get to my neighbors backyard. Police were called, btw (and they couldn’t do anything because they didn’t see him do it).

Any recommendations for metal fencing companies?
