I've got to agree with Dishnu and Ice.
While I'm all for leveraging technology to make the job easier, the time and money wasted in setting up tracing templates is not really worth it. There is nothing too difficult to lay out manually here.
Don't get me wrong. Doing 1:1 plots has it's place.....if you are doing odd or difficult shapes to layout (like an elipse), or large irregular cutouts that you want to repeat, or repeating/tapering bulkheads with compound curves, etc.
As you are already noticing, finding someone capable of doing it is already a hurdle. Then, assuming you find someone who won't rape you on the price, who's to say that their plotter is calibrated properly? I've seen several that shows signs of stretching along the paper feed axis. The print head may be calibrated but pinch rollers slip!
So you're sourcing it, paying for it, re-verifying it, cutting it out, taping it down, tracing it out ....then cutting lumber?!
Sounds like a whole lot of extra hassle, to me.
I say, Man Up
and get cozy with your inner craftsman.
