3d Kitchen Design Software

Can you give me a Mac program for creating a professional carpenter?
My friend is a carpenter (yes I know, it is unusual for a woman, but there ya go) and I'm trying to help her, the right professional drawing program for the planning and organization of their work (with the format Mac OS X). We talk about plans for nursing homes, such as shelves, cupboards and kitchens. The main feature will be natural that it 3D drawings, calculation and measurement to make in millimeters. It will also be good if the plans will be able to be attractive and reasonably realistic, so that the customers are happy when they factor shows them a printout. Price is also one, so if there is a really good and appropriate open source program that we would be pleased. However, we would consider it worth perhaps few hundred pounds to get the best software. Any recommendations?
Google SketchUp. It's free, and it seems more enthusiasts with wood work, it be. There is a forum for wood work and blog at http://www.sketchucation.com/forums/scf/index.php http://blogs.taunton.com/n/blogs/blog.aspx?webtag=fw-designforum, both with some traffic.
