可否幫一幫忙翻譯成英文?? (急)

Thank you for offering us a favorable price (優惠價錢)
Unfortunately, our customer still think that it is a bit too much for them. If they are ordering 3-5 tons, would you be able to reduce the price to US$5,480 instead? I am so looking forward (好希望) to having the business dealt (交易成功).

好感謝你提供優惠價錢給我們!!
但客人仍然覺得價錢太高, 可否再幫忙減到USD 5480 如果客人只訂購3-5噸?? 我真的好希望我們這次可以交易成功!!

Thanks a lot for the good price offered.
Yet our client still thinks it's too high, can you reduce the price to US$5,480 if we order 3-5 tons?
I really hope the transaction can be done successfully with your co-op.
