How much would it be to get my iphone screen fixed?

I live in hemet california btw.
i was just wondering how much would it be to get it fixed? The hole screen cracked its really bad D:
what's the cheapest place? And i can't get a screen from ebay or whatever cause i don't have no one to take off my broken screen and put on a new one.

The cheapest place i think is ebay of course.
