Hi Paul, hi folks. You wrote it correctly when you stated that this takes some time. Now, for someone to make what you want needs that: 1 - The person know this kind of work; 2 - The person take the time to produce the model. This is called professional work and I know of no one that would do that for free. If you just want ideas, this is another game. Some SketchUp user may find some spare time to illustrate it with SketchUp and produce a simple model. Of course, you will not be able to get a construction permit with such a model. Just ideas.
