It is much more difficult than 1 hour to setup yourself, because of FCC regulations flashing new routers is much more difficult, you need a TFTP server, it's pretty annoying. In addition the edge cases of the internet going out, then when it comes back bringing the VPN back up automatically, being able to switch PIA accounts / countries easily, it's not a simple thing. I got into this because I wanted to build one myself, and I have a friggin master's degree in CS and it took me several weekends. So I figured a business could be formed :)
