Plasma Cutting Cardiff / South Wales

[nospark]

I've got a very small piece of flat car panel that i need cutting (just a 6" x 3" rectangular hole with curved corners). The panel to be cut is also small and off the car. I'd like it done accurately with good edges so assume that plasma cutting is the best way to go . Can you recommend anyone in the locality who will do such a small job and cheaply.
