Take a look at that. I've replaced a few cracked screens myself, and they're usually pretty straightforward. The link was just the first example I found, but considering it's $50 and not $150+, I'd take a shot at it.
Okay, I might as well just get this one on amazon then (2 day shipping).
I'm just concerned about the negative reviews... Some people are complaining about screen quality, but perhaps they are incorrect

" Do not buy this lcd display...mine started lifting on the sides after a week. And the display had a yellow warmth display to it, not crisp bright display at all.
Compared side by side with my son's brand new LG G4, this screen is washed out, white-washed (especially wallpaper), as if GAMMA is cranked up too high. I'll assume this glass display

Double tap does not work, bad color saturation, erratic touch sensors, can't even hang up the phone in the middle of a call. The list goes on.
It looks like there is now a screen + frame assembly that is available via Prime, link below.
