where can i go to get the big 3 done?
Why not do it your self? If its something you don't want to attempt, any audio shop or auto mechanic should be able to do it for you.

would doing the big 3 in 1/0 be over kill or what would be the biggest you guys would go on the big 3
I always use 1/0 for big 3, its a bit over kill for a factory alt but its a must for a ho alternator. Just use 1/0 and you have room for upgrade.
