Best Guitar Gear for Melodic Metalcore?

I'm shopping for new guitar gear, I play in the Style of The Word Alive with a Motionless in White twist, I have an idea of what kind of guitar I want (Schecter Blackjack ATX - Solo 6) But I have no idea how to shop for an amp and pedal set... All I really know is I want professional Amps, even if I have to buy a soundboard and monitor system. A price estimate would be greatly appreciated, same with sources.
