Build a Bra sizing widget / questionnaire plugin or popup for Wordpress site

I want to create a sizing questionnaire for our current site - [login to view URL] - I would like it to be exactly like the one on [login to view URL] but with less questions. Also need you to design images just like on [login to view URL] "Fit Finder" feature. I have the questions ready and depending on the answer it will determine the proper size for the customer to buy and collect valuable information along the way which I would like to track in a database that will be sortable based on all responses. The only thing that matters is the band size, so if 38 or larger it's L/XL. If the size is 36 or smaller it's S/M. ONLY 2 sizes, S/M or L/XL. We are collecting this other information for our purposes. Fill out our quick 30 second RxBra Fit Finder and receive 25% off your order! 1) Have you already had your breast procedure?
