Form --> pdf send to customer

Hi, We need a form extension where partners of our company can fill out a form with contact details and when a partner press submit a pdf is created with the input from the form and an offer is send to a potential customer (+ copy to partner and a copy to web page administrator). The pdf must be editable so we can change the text later. There must also be a field in the form which decides the text in the actual mail. Regards, Jon
