How can I upgrade user role after they subscribe?

I am looking for a way to upgrade my users roles after they pay for services…

I have tried a lot of the membership, and subscription plugins but I haven’t found one that provides a php string to hide elements of the theme.

I currently us;

<?php // add a private menu
if(current_user_can('contributor' || 'administrator' || 'editor' || 'subscriber')) : ?>

to control which user role can see certain parts of my theme… Most plugins I have found so far only hide chosen content inside the post itself.

Does anyone know of any solutions???

(or)

Does anyone want to build me custom plugin that works with the above code to control users…? I will pay for quick results…
