Hi!

I’m ready to implement PayPal as a new gateway, but not immediately. Currently, other tasks
have higher priority, so the earliest I can work on this integration is in about a month.

If you (or anyone else) provide a tested PR implementing PayPal using the existing payment
interface, I can review and merge it much sooner.

Waiting for implementation)

I need some time to figure out. I'm not a coder)
