You have Epoch but they will overcharge you for using Paypal
Keep in mind that NO normal PSP will process PayPal on your behalf. There is a difference between covering the payment method Paypal (= you need your Paypal account, you open it, enable it, and connect it to the API of the PSP. You are the merchant of record) AND processing with Paypal without having your own PayPal account (the PSP will use its own PayPal account which is illegal btw but not your direct issue)
Anyway, processing with the second option is a big risk and expensive
