Dear teacher,

Could you please review my text below ? (i think there are some mistakes ):
"I kindly ask your help to do it yourself on my behalf"

"Could I please ask you to do it on my behalf." (I'll owe you a beer) ... or whatever is appropriate.
You'd probably need a reason.
"Since I will be out of town that day, could I please ask you to do it on my behalf?"
