Multiple submit buttons but continuing a form

I would like to set up a form with a couple different steps. I want to create a pricing quote based on user inputs, then display that quote and allow a user to accept or ignore the quote on the display landing page. Basically:

1. User fills out information on main form, which includes all components necessary to determine a price

2. User clicks "submit" or "next" to see the quote. I would like to capture all of the inputted user information at this point, before the quoted price is displayed.

3. After clicking "submit" or "next" the user is taken to a display page, which shows the resulting price. No further information is required, except that there will be an "accept this price" button. I would also like to capture the data again if they click "accept this price"

4. If the user clicks "accept this price" they will be taken to a third landing page, a typical thank you page. 

It doesn't look like I can do this easily with the page break feature, as the "next page" wont capture data as a submit button would. The submit button doesn't really seem ideal either, because I want to "continue" the form on the second, display page after hitting submit.

I posted this privately earlier but reconsidered and thought it would be better to have it open. I've seen some similar issues out there
