i NEED TO SET UP PayPal with WORDPRESS cPanel for payments processing.

I have (my company)a web site already build .I need to set up PayPal and WORDPRESS cPanel payments.I need to build four different $ -pricing table for )(4 packages._ 4 pricing tables. How it should work:A costumer logs in with (has already registered)hi/her email and password. After he/she chooses a package out of the four. clicks on package anditwill take them to PAYPAL payment center ,after the payment is completed successful it takes them back to website package he or she clicks on the button (or without button directly go to open page , and they have to enter all their information of the property and upload pictures). This page ere they upload pictures and ad information about the property already is build,exists in the web site (WORDPRESS) and opens the package (NOTE: package cannot be opened without first reviving payment .or successful payments through PAYPAL) . NOTE each package is for 30 days only. When he/she is fished uploading all he information ,they click on button (already there exists on the page) push button PUBLISH and the property will be seen on the web site. A after 30 days that the property is advertised it will automatically remove (expires)itself from the web site and will no longer be there for people to see. When the property is first published it automatically appear for one day [login to view URL] Todays Listings.(as well on top"Properties Showcase"on the top of page) ( Properties showcase is were all the listings will appear regularly for 30 days and he/she clicks here all properties will appear from deterrent prices and areas)this way people will know that it is a fresh listing and after 24 hrs it will disappear from "Todays Listings" posting and will stay on the web site for another 29 days on "Properties Shwcase"
