Create html / php price quote form

Please look at? <[login to view URL]> In the middle of the page there is a price quote form located here:? Wedding Photography Package Designer I want a similar quote system whereby the form is almost identical to this one and when someone clicks calculate they receive their quote instantly. The price quote would be based on a .txt file that would have values for each option, ie. 1 or 2 photographers = price X 1 or price X 1.5. The results page I assume would be .php.? I want the results to appear with a 2nd form with name, phone#, email address such that when they type in the information it takes the first form, combined with the 2nd form ane emails it to me using php.
