oh wow - was this thread really started in 7/2019? i have the same question myself...
long story short: i have a 2003 nissan frontier, and a few years ago bought a 3" rancho lift kit from 4x4parts.com. had them installed by a local garage here in berkeley, ca. that particular rig is showing its years, and it's time to let it go. as for the install, i feel like they did a really decent job. they do, after all, participate in some race where their entry rig was a lifted jaguar coupe or something. if they can mod that kind of car with a lift, then lifting a pickup would be a cake-walk for them!
we just bought a completely stock 2015 tacoma as our new family car, and my wife is allowing me to lift it sometime down the line. she said she'd rather it get installed by a garage that knows a thing or two about overlanding (we're both fans of the xoverland.com team and their show). so yeah - kind of the same question as you. is there a garage around here that specializes in this kind of thing, or is it fine to just have the work done by a well-reviewed garage?
hopefully someone else chimes in soon!
