以下の通り会うことの提案に歓迎を頂きました。
Sure, you can come and visit our office although it is a small e-commerce office that we don't have too many stock for you to see. We have very good relationship with distributors in Hong Kong that we usually can get products form them in a few hours, so we don't stock too much.
Please let me know the date and I can email you my mobile number for you to call me in Hong Kong. 20th Wednesday will be a good one?
Don't worry, I have many Japanese friends and I can understand what they are talking about. :)
