Paypal Recurring Payments in Wordpress Website

Hello to everyone, We have a wordpress website named "[login to view URL]" It is a directory for listing wedding vendors. When a vendor is signed up he has his own back end ( [login to view URL] ) with pricing plans. When a vendor press to pay the plan it comes up a paypal button. In the theme option you can set up the paypal with this attributes ( [login to view URL] ). When you buy a package it comes up with some option like to define how many listings you want ( [login to view URL] ) We would like to develop the recurring payments as below : 1) We want to charge every month the vendor via paypal and give him the paypal invoice 2) We want the template to work fine ( when a vendor pays with recurring his listings will be visible to web visitors, when he is unpaid the listings must not be visible to website visitors ) 3) When a vendor pays with recurring he must be able to work fine in the website and make his listings etc etc Also there is a wedding couple back end where the couple defines its name, phone, email and wedding date. We want when a couple is signed in, the system remembers theese attributes and whenever they want to send an inquiry to a vendor the following fields ( [login to view URL] ) to be pre-filled If you find it difficult to develop something in the front end because it is at the greek language we can remove the .po file from the loco translate and work fully in English language Thank you very much
