Hey there,
we are planning to launch our very own international mainstream dating site and wondering if someone could recommend some trustful payment providers who can proceed subscriptions (whitehat) in globally like US, UK, AU etc.?
PS: If here are any dating veterans who already ran their own site and would like to connect, I'll be more than happy to receive a pm from you. We smashed the dating vertical during the last year heavily, so definitly can provide value back.
Quite an easy solution here, check some of the major dating sites, try to join and check who they use for payment processing 
I checked a few for you, they used paypal, skrill and digipay ... digipay seems to be used by the top dogs like match.com
Well it's not that easy cause most of them use some whitelabel solutions where you won't see the payment provider on the website, probably just through the source code, but thanks anyways regarding @digipay.
verotel and maxpay are good ones to start
