More than you think. I've done about of dozen of these on various cars and suspensions, ranging from simple damper installs, to damper AND springs, to coil overs, to coil overs that came with camber plates. And I've done this with various tools, ranging from the harbor freight special ($20) compressors to fancy hydraulic units that has the adjustable arms that you just pull a lever to compress.
Not trying to come across as a know-it-all, but I have done just about every combination of suspension install you can possibly imagine on a MacPherson strut. That's why I say it's not as simple as most of you may think, and the time to install may vary heavily on the type of tools you have on hand and the type of suspension you're installing. Any shop quoting $120 for an install without finding out what brand of suspension and what condition the car is actually in, are going to be in for a big surprise.
