If you start with a printed outline of the TVPs with the holes marked properly, then draw over that, you can just scan up your drawing and use a program like adobe illustrator, any Vectric software, or inkscape(free). Programs like these (there are tons of others) will have a "convert bitmap to vector" command that will digitize your hand drawing so that it can be imported into CAM software.
This will of course be an exact replica of your hand drawing, including imperfections. If you want to have perfectly straight lines and radii on the flames, you will have to find someone who's good at CAD design to start from scratch, or potentially just alter your hand drawing.
