um...the chances of you finding a good shop that does good paint jobs for 800 bucks is highly unlikely. Not around here anyway.
However...i do know of places that do great great great work and decent places as well.
Top Car Auto Body in Hillside.....a legit paint job is gonna run you 2-4 grand. also...
Sal Mar Auto Body in Newark,NJ....about the same price range.
there's a buncha shops : Miracle, EuroStyle, Motor City, Lusamer ...all in Newark and all do good work. They are a little less expensive then the 1st shops i mentioned. Thats all I can think of for now...I know a few shops in Union County but i cant remember the names off the top of my head right now.
