We are looking for a Windows web hosting service for our official website.

Currently, our servers are located in Vancouver. Our main customers are from United State and this is why we are going to transfer our official website from Canada to USA.

Here are some main points we care about the hosting service mostly:
The service must be stable and safe. This is our OFFICIAL WEBSITE. You can imagine how horrible it is if the official website cannot be accessed.
The bandwidth must be fast and stable. We have customers and visitors all over the world. Currently our daily PV is more than 30,000. We want our visitors or customers in any place can access our website fast and smoothly.
The machine hosting our website must be very powerful and we do not want hardware resources of the machine to be shared with too many other websites.
Our website must have an independent American IP.


Can you give me some suggestions?

Thank you.
