请英文高手帮我写一封要求订单加数量的信。

Dear xxx,

Sorry to trouble you, while we really encouter a problem that the current order quantity could not cover our cost.

On the one hand, since you know, the current order quantiy is only 2-3 cubic meters which couldnot feed a container, therefore we have to ship out by LCL (less than container load). And the cost of LCL is relatively higer than FCL(full container load).

On the other hand, by the way of LCL, we could not clear custom in local. We have to go through other port. The custome in that port always inspects our products and we need to handle the high inspecting fee.

As far as I concerned above, we really hope you can rise up order quantity to xxx (这里填你希望提高到多少) for the sake of long term coopration. Thanks great for your help and understanding.

Regards,

xxx
