need suggestion for a invoice subscription plugin or hack

Hi all,

I’m trying to setup a sort of webhosting site where the user can buy a plan (via paypal or credit cart)

So basically the user should make the subscription and payment in one or two step, and then something that remintd me or the user when a plan is expiring.
I’m at today I’ve found some interesting plugin but nothing that can do what I want…it would be perfect a sort of member subscription + recurring invoice.

For example the wp-invoice plugin is great for the invoice when a item is expiring but for what I understand there is no way to place a fixed signup form with payment (the subscription part )

So that step could be done with a membership plugin but then I’ve not found anyone with a recurring billing for the clients.

I’ve checked also some cart plugin but all are to bloated for what I need.

Can anyone give me a hint? Oh the plugin should be possibily free ??

Thanks,
Nunziob
