I Want To Buy Desktops In Bulk, About 10, 000-20, 000

Only need suppliers of New Desktop Computers in the United States.

Hello,

My name is Welensky Nathan, the owner of Cadson Investments LLC here in the United States.  I spoke to you today about the purchase of desktops in bulk.  I recent got a contract to supply desk tops in Nigeria. I have a couple of questions:

1. How soon can you fulfill an order of 5,000-10,000 computers?
2. Do you ship to Nigeria?
3. What will be the cost of that order and shipping to Nigeria?
4. If I remember correctly, you desktops here on Alibaba.com came with the monitors, if not, howmuch will a complete computer set cost?
5.  Lastly, what form of payment do you take and please explain all you will need from me. 

Thank you,

Welensky
