I've come across
PChome Online 網路家庭-交友, which is a dating site but maybe I'm seeing a bit more. I can't read Chinese.
PChome Online 網路家庭-交友
Browsing through this I see a lot of direct contact information, prices such as 2000-3000 for 2 hours, and pictures with maybe additional albums. Seems to solve the problem of having to rely on luck with girl quality/age, being overcharged, and only 50 minute session. Will try it myself, but I'm already over budget this month.
Let me know if anyone tries this.
