PDF invoice creator

Hello.
I need a module for my webstore.
I can not understand what to chose.
I want it to do next.
When people place the order, the module generates the invoice and sends it to the customers email address,
The invoice contains a bank details and all informaion to pay it.
Which module should i use for this????
It will be as a payment method too, receive it by email, pay, and then the products will be dispatched.
Thanks
