Flash: Build Your Own (Similar to Timbuk2)

We require a "build your own" flash file similar to the one at [login to view URL] (http://www.timbuk2.com/tb2/products/bagbuilder#/sizeId=4&customProductSetId=2&uid=31640) Our product is a car seat, not a bag, but the principle is the same. Our product will have one fabric for the center, and two side panels. The side panels must be the same fabric. Additionally, the customer may choose to have words embroidered on the product. We will provide you with a drawing of the product. Sample drawings available to qualified coders upon request. There are currently five products. We will want the fabric samples to be loaded from a directory or array of jpg files for future expansion possibilities. If a new product is to be created, I would expect a new fla/swf file to be created. So this project is for five fla files, all having similar function. If/when new product lines are added, a new fla/swf file will be created. It is my preference to have a flash file that I can easily load properties & information via javascript - for instance, when the customer chooses the words to embroider I will pass that to the preview window via JS rather than having the input box in flash. I will also create the entire "wizard" layout myself using html/javascript. The end result of this project should only be a small flash file that is a preview of the actual product. If it's easier, I can even pass the url to the jpg file of the currently selected fabric sample and you just load it in to the preview (rather than looking at a list of jpg files yourself) If this is not the best way, please advise.
