OT: need an assist --> cutting a ~30mm disc from a metal plate

[wallymann]

have a small sheet of...basically iron, roughly 3-4mm thick...and i'd like a 30mm disc cut from it *without* a centering hold left after the cut.

does anyone know of a service where i can send in my stuff and they'd do this for me? or even better, any paceliners have the equip to do this? id pay for your time of course!

also, the "iron" is actually meteorite...so its a 4 billion year old artifact, so i'm super keen to have this done right! living in detroit, all the machine shops around here seem to be focused on industrial-scale activities...some random guy with something like this isnt something they're keen to take on!
