"A fret job" is replacing the frets, in my lexicon - panic!

Leveling & crowning the frets is something else entirely, about $150 cheaper for one thing....
Hold each string down between the 2nd & 3rd fret, and look at the space between the string and the 1st fret. Different people like different things, but a "standard" height there for the high "E" string is roughly .010" - the diameter of your high "E" string. Every guitarist and their dog needs to buy Dan Erlewine's book, "Guitar Player Repair Guide", so they can learn this stuff and (eventually) save themselves thousands of dollars doing their own work. He lists some standard heights - for a Gibson straight out of the factory the heights were .030" to .015" from the bass strings to treble, his own guitars are adjusted .015" to .009" bass to treble.
You certainly don't need a full set of files, as any file can be widened with sandpaper - it depends on how often you do this stuff. Erlewine explains all this and how to do it. Most of my favorite files aren't "guitar" tools, especially a little flat triangular guy that'll widen slots without deepening them.I tend to go as low as possible, but with the knowledge that I'll have to either raise the nut and recut it, or make a new one, every few years - stuff wears. It's no big deal to
me but it takes a few hours and you need tools, in my case a magnifier is the most important tool of all! (Hint: don't get old....) People who bash a lot of cowboy chords while they're singing will tend towards the high side, if you're strictly a slippery lead guy not so much height is needed (Cowboy Jerry Garcia - .030" across the board! Slippery,
too :icon_scratch
