麻烦翻译下英文

请大大们帮忙下
=============================================
有2点事项:
形式发票上的内容显示单价是EURO0.640
你们有给我们折扣3%的优惠

1 如果可以改成单价EURO0.621最好,以便我们付汇

2 如果单价按照EURO0.640我们下个礼拜先付EURO20000.00给你们

余款将在总价EURO64000.00折扣3%的基础上付给你们EURO42080.00
不过这会在结算时有点麻烦.

请尽快告知最终的形式发票.
========================================================

不推荐用GOOGLE上翻译的,谢谢!
