Recurring billing solution for website

Greetings all-

I run a membership website with a few thousand monthly subscribers. I'm
looking for a billing solution.

Specifically, I would like to:

1) Automatically charge clients cards every month (recurring billing).
2) Have a web based virtual terminal where I can manually setup/manage
clients.
3) Have an api so I can push a URL to setup/delete a new recurring
charge/client.
4) Have a customizable email invoices sent automatically prior to the
recurring charge and a receipt sent after the charge.
5) automatically notify clients with denied/expired cards via email and
and allow them to update their cards via a web form.
6) I would get emailed about delinquent clients.
7) Have the service push a URL to a page on my website with variables I
can define (so I can automatically block out unpaid members).
Allow clients to login and view past activity/current

Does such an animal exist? I envision this as an online service. I've
looked everywhere and everything seems to fall short. #7 is really
tough to find. #8 isn't imperative if i can get #7 to work.


Thank you!

John
