Heres my help MewGirl, but firstly, Fowl Inc, you're not supposed to advitise your own threads in someone elses:
Charizard @focus sash/ Expert Belt - Physical Sweeper
Adamant (+atk -sp. atk)/ Jolly (+spd -sp. atk)
Blaze
-Flare Blitz/ Fire Fang
-Arial Ace
-Earthquake
-Swords Dance/ Dragon Dance
Flare Blitz and Fire Fang are for STABs. Flare Blitz is the most powerful, but has unfaverable recoil. Fire Fang is significantly weaker, but prevents recoil. Arial Ace for STAB. Earthquake for good coverage and power. Swords Dance and Dragon Dance are good stat raisers. Other options for him are: Brick Break, Rock Slide, Dragon Claw and Shadow Claw.
