Need urgent help with paid membership pro plugin to add another payment gateway to membership site

Hello I have a membership affiliate site built in Wordpress using AffiliateWP as well as the plugin PaidMembershipsPro. I need someone today as soon as possible, to walk me through on screen share how to pay for the plugin, add stripe as well as test Paypal as it is not working. And potentially add other payment options. This is urgent as I have members who want to sign up today but were not able to.
