I'll do something similar to what I have done for my OZ sites.
The public pages are free and everyone can view them... these will include listings of escorts and massage services similar to what you see in the yellow pages of which Mah Bow Tan is a director. If that is lawful then my site will be lawful too.
However, those who want more details have to sign in for a small fee for the more juicy details. The sign in will take them to a separate site.
I need to see whether I can use the same script with modifications or whether I have to rework the whole system.
Take a look at what I have done for
www.newzealandgirls.co.nz.
The Premium Lounge contains the details and the reviews. The public area contains only the bare essentials.
It is quite common for companies to set up offices in different jurisdictions and adjust their practices according the laws of the land in which they are operating. For example if I had a Singapore company that also had a branch in the USA in the state where pot is legal, as long as I did not import the weed and consume it in the Singapore office, no laws would be broken.
The legal details need to be worked out by the professionals but I'm sure it can be made to work. Nothing is impossible.
