Seriously, there are several places to get them but you have to hunt for the good ones. Many are surplus military or used aviation equipment.
I'm not a real expert on them, but from what I understand, this particular model is roughly 1,000 hp. There are much larger sizes and varieties, some producing upwards of 2,000 hp each.
This turbine has a story and ties to our group many years ago. Lee Roth used to pull parts of this tractor back in the eighties (I think the engine and fenders). Greg bought this one down by Jefferson City, MO.
Expertise? Not much of that here but they say once you get it set up, it takes very little to maintain and operate. So far that is true. I have seen motors around for as little as $2,500 and as high as $25,000. I guess you just pick your poison.
