Guys, you really need to learn to do basic maintenance such as action adjustment and intonation etc. yourselves. It's plain insane to have a tech do such menial tasks. Even correctly tuning a guitar is arguably harder to do than a basic setup.
I live in a climate where the humidity changes from 20-90% and the temperature from under -30 to 90's F and I do some neck adjustments on some of my guitar on practically a weekly basis. Sometimes I've done it in a few minutes before band practice, it's that easy.
Same with intonation - I use pretty much whatever strings are handy, so when I change strings I also adjust intonation. Takes less time than the actual string change. Sometimes in the studio I've adjusted intonation between takes - again something so easy even a blind monkey could do it no problem.
And again the same with bridge height adjustment - just raise or lower it as you like, what's so special about it?
The only thing I'd say is a bit more tricky is lowering the saddle, and that is very often what's also wrong on budget guitars...they always tend to be a little too high, and also sometimes the 1st fret is a bit too far. But even that is nothing but a tap to loosen the nut, file it down carefully some, maybe file some of the fretboard wood if need be, and a few small dabs of glue plus pressure for 30 minutes and it's done. You don't even need much tools beside some 400-800 grit sandpaper.
I guess it can feel a bit intimidating at first, but it's certainly no harder than, say, changing the oil and tires etc. on your car. Nut work might be compared to something like changing the battery, the exhaust or the alternator, but anyhow super simple stuff. LEARN IT the web is full of instructional videos and helpful guides. I was toying with the idea of making a 10-minute video where I put together a cheap guitar and adjust the neck and nut and all, but seems there are so many vids out there there is no need for one more.
Which reminds me, I need to go file the last few frets on my V ever so slightly lower...I gave it an ultra-low action and it hangs slightly on 24th fret when I bend a full bend there now...needs some TLC with a sanding stone and 0000 wool afterwards...
