did it myself with a film strip kit for about 15$, not a big deal works best with two people though. rule of thumb is that you dont go below the mirror mount. your windshiels may hav a small line marked abs1 and an arrow in the upper corner, usually on the passenger side. you can not legally tint below this line. you definately cant tint the bottom of the windshield which i have seen on the street as well. the job goes easier if you remove the mirror from the mount (set screw) but leave the mounting plate on the glass.
