New to the game / Starter army

At best I could get 449 points giving everything the most expensive upgrades I could think of but the gist of it would be the kabs get a splinter Cannon and a blaster, the syberite in the kabalites unit gets an agonizer, Phantasm grenade launcher and a blast pistol, the reavers get a heat lance and grab talons, the arena champion in the reavers gets and agonizer, the raider gets a Disintegrator cannon and shock prow and the Archon gets a husk blade, Phantasm grenade launcher, and a blast pistol. The Archon will be on foot and your kabalites will wanna be at about the 12 inch range for Rapid Fire, the reavers will take whatever drug you want them to take. But really try all the weapon profiles and find what you like to use, I was just trying to make it as close to 500 points as possible, if you want to get to 500 you will have to add at least a small unit of something
