请高手帮忙翻译一下下面两个句子 ： 拜托了

1. I hope we can understand (the situations of) each other and keep the reciprocal trading relationship. Waiting for your confirmation.
2. So that we can only use the same undyed material as the Remi hair to make the hair in light color.

括号内的可以加也可以不要.要了意思更委婉点

1.I hope that we can understand each other, and continue our mutually beneficial trade relations.I am looking forward to your reply to the confirmation.

2.So we can just use the same hair materials without staining as Remi hair to make
light-colored hair

你需要翻译成英文还是日文还是......
