I'm going to try my luck with http://www.pcbweb.com (free schematic and board design) and http://dirtypcbs.com (+/- 10 boards 5x5cm for $14 including shipping).
Now only to find the time to start putting it together.
Hello, our tool started out as a web tool using silverlight and we transitioned to a desktop tool (see second bullet above). We still have a lot of web features like our publish widget.
See example published project: http://www.pcbweb.com/projects/ZYmV7nDMlE24cAauFYhec8H8rBdKro
