Looking for a premium membership plugin

Hello,

I am looking for a plugin that allows users to pay a certain amount per month (£3) via paypal which then changes whatever account they was logged in with at the time to a different user role (Premium) in which I created via User Role Editor. This is quite simply all I need and most of the membership plugins I have seen are too complicated and do not match my needs.

All support and suggestions would be much appreciated.

Thanks,
Elliot Sowersby
