I would like to ask you about running a Dating/Marriage site in my country/state

The marriage/dating sites in my country allows to search for profiles free of charge and charges a hefty amount for the contact details. They charge like 60$ for 3 months or 120$ for 9 months which I think is a little high.

1) Are there any reliable providers of these sites. What I meant is like a forum provider.

What I would like is to not charge users for anything ( as of now) and probably depend on CPC/CPM and any other means of earning money.

All inputs greatly appreciated!.
