我願意為了你...

No
可翻譯成:
I am willing to ??? for you
(???=睇下你話佢願意做咩)

有一首英文流行歌"Everything I do, I do it for you.意思是我所做的一切,全都是為你.另外有一美國俚語I will do whatever it takes.我會不顧一切去做.例如I will do whatever it takes to protect you.我會不惜一切去保護你. I will do whatever it takes to 物物代表我會不惜一切去物物,這樣才可係後面跟to嫁.唔可以講I do for youi to 物物.I do for you應解做我願意為了你而做某事.

Yes, but i think u say what will u do for him/her will be better.
