CADCAM Application ReWrite

We have a Windows Vista application wrote in Visual studio 2005 C#. We have recently moved it onto the Visual Studio 2008 C# Platform.? The application is for the most part working but still needs to be extended in some areas.? The APP is a basic 2.5D CAD package working with DXF files to output GCODE for CNC routers and milling machines. We require someone with an artistic flare and an understanding of CNC Machinig to work on all aspects of the Visuals and the user interface.? The displayed models are wire frames and need to be optionally replace with a graphic solid representation of the model being created from running the GCODE. We need to add a post processor editor to the CAM output side to enable the user to taylor the GCODE output to the requirments of their machine. We can point you to look at the competion and how they handle their GUI.? Our interface is very technical and need to be transformed for 2009/2010 look and feel. The object is for a c programmer who is very competent with visual studio application do introduce his/her impression of the future.? Includes buttons, solids, spped controls etc. The winner of this job will most likely get more jobs on a good completion of this one. Cheers DeWayne
