User Experience Redesign for Woodworking Design Software

We are looking for a room design 'front end'. Basically it will allow users to specify room size, add walls, select cabinets from a list, and locate the cabinets in the room. There will be room constraints - like spacing for doors and window. Cabinets will be fixed sizes. The location of cabinets exist as both a floor plan and elevations. 3D images would be desirable but not required. We are interested in a very intuitive process creating a room full of cabinets. This can run as a web project or a desktop application. This includes but is not limited to: Creating a a design repliacting the process or flow of populating a room with cabinets. Creating story boards showing the potential flow, screen designs, and menu items. Developing wireframes or other mockups of the new interface[s].
