donation help

I was wondering if any one could make me a script for a site that will allow people to create their own custom weapon/armor and it increases the price as fields are added/increased then it sends sql to a email to have put in once the money is received. Similar to Undamed - Wow Private Servers - Support World of Warcraft WOTLK 3.3 would be nice if it would show the price at the bottom of the page so they know how much they are paying.

Would be very greatful if some one could.
