Build a kitchen design plugin for website guests to configure and submit cabinet selections

We are a remodeling company specializing in kitchen and bathroom cabinets and countertops. We would like to add a website room design tool for clients to configure their kitchen or bathroom. Here are some of the details: ROOM LAYOUT AND DIMENSIONS 1. Wall pattern templates to select from for Galley, U, L, Batwing, or custom 2. Adjustable wall dimension tool 3. Simple drag and drop feature for window, door, low wall and pass through placement CABINET SELECTION AND PLACEMENT 1. Catalog of generic cabinet for drag and drop placement 2. Default dimension tool for wall cabinet height 3. Incremental cabinet width tool 4. Default cabinet style/finish selector TRIM SELECTION AND PLACEMENT 1. Trim selector tool for fillers, crown and light rail molding, glass, etc. Users will need the ability to view a 3-D rendering, save, and submit the final design. A materials list generator would be useful if it could be included. We have looked at several trial downloads, but have not found a program that contains all the features we require in a SIMPLE format that users can easily navigate.
