是 thank you for you to help me还是thank you of you to help me.

你是想要表达谢谢你的帮忙的意思吧，不用这么麻烦，thank you本身就是谢谢你的意思了，后面就不用再写for you 或者of you了，直接写成，thank you for helping me就行了
thank you for doing sth为做某事感谢你，这是一个固定词组的，举几个例子吧：
Thank you for listening谢谢收听 thank you for coming谢谢您的光临

Thank you for this food.谢谢你准备的食物

希望帮到你，祝学习进步

是 thank you for you to help me
不过一般不这么麻烦的说 直接thank you for your help. 或者I am thankful for you to help me
后面那个应该这么用：It is kind of you to help me.

thank you for your help比较好
或者是thanks for your help

thank you for helping me 或者thank you for your help 就可以了 简洁
thank you for you to help me也是可以的咯 语法没有错 就是表达太中国了 chinglish

thank you for your help 或者 thank you for helping me.
你那两个句子怪别扭的 不过语法上应该是thank you for you to help me.
