Can't see the image, but you'd probably need minimum 500watts in a fiber, probably minimum 1kw Co2, less if you went with stainless. Plasma if done right can hold pretty good size, i would think < 1/2mm tolerance would be easy. Hypertherm or a miller on a CNC table would be my choice. A good brand 200W fiber for just the power supply and fiber is 30K, not including heads or a cnc base.

For 20K you should easily be able to get whatever size plasma table you want and a top notch plasma unit.
