What are the speakers mainly talking about?

M：Amber, we have to find a suitable place to meet with HA Systems Co. Did your broker say how long it’s going to take to process all the importing documents and customs forms?
W：Yes, Brian. I was told it would take at least 14 days to process the international shipping documents.
M：That sounds good to me. I thought sending documents back and forward to London would take three weeks or so. Are you planning to go to the meeting by yourself?
W：Actually, Melissa will be there, so I can be working in the comfort of the main office here in Seattle.
