Honestly, unless you need your frets dressed (if they feel sharp like they're sticking out too far on the edge of the neck) get yourself some hex keys and little screw drivers and do it yourself.
There are a ton of youtube videos about setup and other resources out there, but it's all pretty intuitive. If your truss rod needs to be adjusted because you have too much/too little relief, do that first with the strings tuned to tension. After you're happy with the truss rod, set the action by adjusting the saddle heights, then check the intonation with the 12th fret harmonic. If it's flat or sharp, move the saddle forward or back accordingly.
Make small adjustments at first to make sure you are going in the right directions. If your truss rod won't turn, try the opposite direction. There's a chance it's as far as it can go one way or the other. Otherwise if you do something wrong you're just turning screws anyway, so you can always turn them back. Leave some of the more intense stuff like fret dressing and cutting a new nut and things to the professionals, but simply lowering your action or getting the right truss rod relief really doesn't need to cost you whatever some guitar shop is going to charge for it.
