Yeah, you need a decent base to start from, since there's not much you can do about the pattern, the fabric, or the construction of the seams you're not going to alter. You also need the shirt to fit in the shoulders and have reasonably high-cut armholes if you want to end up with a decently slim fit.
You'd need up to five alterations - tapered body, slimmed sleeves, cropped hem, and back darts x 2 - to get all of the details, and you need a tailor who's not going to mess it all up. I'd say you can easily drop another $20 - $30 on the alterations, definitely more if you're going to an expensive tailor.
I'd say the best bang for the buck for button-up/button-down shirts is going MTM.
