Dear merchant Aosen,
We can start deliveries of 600

per

immediately this week.
We suggest that we set a guaranteed period of 15

, after which the trade continues on indefinitely and is cancellable by either side with a cancellation notice 5

in advance of the actual stopping of trade. We would like a payment of 0.25

per

.
We am, of course, open to negotation on any of these terms.
I look forward to your reply.
With kind regards,
Duke Iaat Vyapar
PS. As an aside, I am glad that you have given an indication of the amount of growth possible in this trade, and I will keep this in mind when directing funds towards improvements of our production processes.
