Help! LLC in Delaware looking for a payment Gateway while operations in Lebanon

Hi All,
Difficult question:
Does anyone know if there is a good and reliable payment gateway provider for my e-commerce website? Given that my company was established in US/Delaware (Single-member LLC, with EIN, no SSN) and I am Canadian. However the operations are in Lebanon.
Apparently not all providers accept to setup a gateway for a company without a physical address in the US, and Virtual Addresses are not allowed.
Thanks, much appreciated!
