how about this.
instead of trying to make money off this if you really care about the safety of the workers.
maybe your team should be writing to your governments to get legal brothels and a sex worker registry up and running.
like they have in Australia. there will always be street walkers but it helps curb human trafficking and underage prostitution and violence.
It is not suitable for other countries. And as mentioned before, sexing service is forbidden in most countries and the market is not so large in my opinion. What's more, safety is the most important problem both for girls and the buyers.
