Curved Roof or Rounded at Ridge and Flowing Over at Edges

[BroderickDesign]

Anyone want to take a stab at setting a file like this up for me? Contact me if so at my email with cost... need quickly.

I need to create a plan file to use in the future for other buildings of this style, they will all have the same curvature for roof eaves and ridge area, I would just change straight planes based on size of building.

The attached sketch is what I would need the general shape drawn to according to the sample rendering.
