irons pull hooks off toe

[WPBgolfer]

guys, i need major help. i have been swinging the club very bad. 80% of my hits are off the toe or fat. i then procced to pulling it a good 30 yards. i have mainly a vertical swing up and down. also i have been taking very big divots. i have no trust in my irons or my wedges as it is also a problem in them.
any advice would be greatly appreciated.
and i play to a 6 if that helps out
thank you,
Michael
