It's probably just a 1 man business, as you can see there's not too much in the contact us section and no 1-800#, you should send them an e-mail. Looks like a good service though, too bad they don't have any China ips.
There are a lot of 1 man VPN services out there. I looked at strongvpn they seem big and let you change your IP a couple times, but they are expensive. I was thinking about getting a vps, I even saw one that said you get unlimited IPs. Of coarse the definition of unlimited in marketing terms varies wildly.
