If you're willing to learn how to do a good chunk of that work yourself you can dramatically cut costs. I'd just be wary of leveling and crowning frets, took me a while to learn that and it does require specialized tools and practice. Truss rod adjustments, sharp fret ends, string height (at the bridge, not at the nut) and intonation are well within the realm of reasonable for someone willing to learn a bit and take a few precautions and they take minimal tools - you can sand or file the edge of a cheap mini file to make a safe edge, I did mine on a belt sander. A cheap set of harbor freight feeler gages works perfectly fine for truss rod adjustments. You can get a pretty reasonable string action ruler off the big "A", but I went with the planet waves one, the dark background with light increments is easier on my eyes. A basic multimeter is really all you need to track down most electrical issues, and the ones you need a better multimeter for are either because you have active electronics or the pickups are bad. Investing around 30 bucks in tools that should last you a lifetime (unless you're me and misplace them constantly) and some time and research on the YT is well worth it IMHO
