I'm in San Diego and my current engine is dieing on me. Does anyone know a shop in the area that could drop a new engine in?

Speed Force Racing on Mission Gorge Road off the 52.

my engine isnt dying on me, buuut its at 185xxx miles and i dont really wanna wait for it to take a **** on me lol sooo how much is the swap? i know i can get an engine for like $700-$1500 but i nvr thought of the actual labor costs. i would hate to overpay :/ and how do you know if a shop knows what they are doing? i dont wanna pay for an engine that wasnt installed correctly or had some corners cut :/
