AJAX Drag and Drop Custom Page

I need a AJAX based pizza customization page wherein the ingredients are located at the top of the page by ingredient group (sauces, cheeses, meats) while the bottom of the page contains three vertical boxes (left half, whole, right half pizza)... Users click on the ingredient pull down menus, drag and drop the ingredients into the respective white construction boxes (right half, left half, whole) at the bottom If user wanted to remove items from the pizza, they would drag and drop them out of the pizza constuction area into a trash can icon OR just off the list and they would disappear... That is the custom pizza scenario... for the specialy pizza, a simple click on Hawaiian from the main restaurant menu would populate the "whole pizza" construction box with all the standard ingredients of the hawaiian pizza... user could then modify the pizza in the same fashion as if were built custom from scratch 1. Ingredients would have to be loaded dynamically 2. Numberous validations would apply You are not responsible for the db... I am constructing that now..... You are responsible only to make this single page work... I only work directly with a coders.. If you are a marketer or business dev person, do not bid... I will not return your inquiry... ... If you are serious about this project... please present three serious intelligent questions about the project which would demonstrate your knowledge of AJAX based customization page..
