It made the news a while back when someone was offering $10k USD to anyone who introduced them to someone he would marry.

I would do the same, but I don't know how to make it feasible without sounding terrible.

I do often let people know I'm open to matchmaking if they know any women my age.

It seems like these dating services could hold the bulk of the money in escrow pending the marriage. Maybe you pay a few hundred up front, but a few thousand in escrow, and when you get married, it gets paid out.

Maybe get the same problem as recruitment agents.

In theory an agent should want to match you to a good job. In practice it's a minefield.
