Your question makes no sense to me. Where in the US are you looking? Any competent person, mechanic and machine shop can remove most broken bolts and screws unless it's in your Rolex.

just use a center punch and punch it dead square in the middle. Use a 1/8" bit for a pilot hole, then use a 3/32", then finally the size you want for your bolt. I like to take the bolt that belongs in the threads where the broken bolt is, then find a nut that fits it. Then you take the biggest bit you can find that fits thru the nut and drill out the rest of the bolt with that bit. Last retap the hole with the right sized tap for the original bolt and it's like nothing ever happened. It doesn't work all the time and its success hinges on how well you center your punch mark.

Re: Technique of broken bolt removal
 
Depending on the bolt, its size, what it's broken off in, and is/was it seized when broken off, there are several ways to get it done; My first choise is to carefully center punch the bolt use a reverse twist(left hand twist) drill, usually as they break through they will catch and turn out the bolt. I know it sounds funny but they actually do make left hand twist drills in a variety of sizes, You can get them at most good machinery or tool sales stores.
Failing that, I try an easy out, if that fails even after trying heating the material the bolt is broken off in to loosen it I usually try drilling it out as close to the thread size as I can and use the correct tap to get the remaining threads out or a torch to get the remaining threads out by heating them very hot then use a pick to remove them before running a tap through the threads.
Last resort is to find an automotive machine shop (Engine rebuilder) most will have a machine that can burn out the bolt...

If you are talking about EDM (electrical discharge machining) then Google is your friend.

Drill a hole in the bolt and then use an easy out.

Use of the term "metal disintegration" leads me to believe he's talking about EDM.
