Might want to consider Adyen, which should support IRIS, the Greek instant payment system.

Thank you for the recommendation! That I couldn't sign up using a form and I had to "talk to their team" was a turn-off for my (extremely extroverted) self.

That usually means you can't afford it unless you have people working for you that do the 'talk to the team' thing.
