Dear teacher,
Please correct and suggest the better ones.

Dear Sir,

Thank you very much for your helping.
I am sorry for replying late.

Before having a certain order, we need some more following details:
-How many cartons will you use to pack for 1,000 pcs of each sample number? (2010T, 2007 and 8004)
-How dimension of each kind of the carton are they? (width, length, heighth)

Looking forward to hearing from you soon.

Thanks a lot

(Suggestion:

In addition to our recent request for estimates on orders of 1000 pieces of sample numbers 2010T, 2007, and 8004, we will need the following information:
Number of cartons that will be used to pack 1000 pieces of each sample.
Dimensions (width, lenght, heighth) of each type of carton that may be used).
