save page to DB

Hi all, I have a page that dynamically produces itself from a mysql db. It produces a form with the prices of scaffolding items and then uses JS as a quote calculator. I was wondering whether someone could tell me how to save the whole page into one field so that it can be reproduced in what ever state it was left? It will not ever be necessary for all the individual fields to be saved, only a few key totals will be eventually stored if a quote is finalised so I am looking for a quick way of storing the page if the quote is in progress and has to be left, Phil
