Is it possible to setup the eaSYNC Car Booking Plugin without the paypal, so tha

it is such a shame that an app that is really great in many aspects is limited only to paypal. in my country the costs for paypal are so high and generally people do not use it for car rentals.
at least add an option where customers can book a car, without payment, until you add more options.
for now this app is unusable for many and I cannot understand how you do not see that.
