Go to full bore, sbt, and SES in pa. They are the typical 3 places people use for pro rebuilds. There might be other shops too, but can't think of them
$1200 bucks is about the ball park. I used Full Bore for my rebuild but if you need it fast or by a certain date not sure if you want to use them. There time frame for rebuild work is terrible (or atleast for me, 3 1/2 months waiting and 1 month behind when they said they would rebuild it and its still not rebuilt )
