If you look through out here there are a lot of good builds. But if you want a really good rushing char make a hammerdin. The only think you need is an enigma, which is a lot and you said you dont have godly gear so nvm. The build you would have to use would prolly have to use dual elements because of immunes in hell.

Maybe a Orb/chain lightning which has been mentioned or a blizz/fireballer maybe. Not sure if any of these would work really well in hell.
