How to install more then one SSL on Windows 2008/IIS7?

We searched about this topic here and found lot of posts that cover different parts from this topic but we didn't find and answer for our solution.

Problem:

• We have Windows 2008 Server with IIS7 and we would like to install more then one SSL on this server.
• We have one IP address for this server but maybe we could get more of them, and we found that we can have only one SSL on one IP address

Questions:

• If we are not wrong, we can have only one SSL on Windows 2008 / IIS7 if we have only one IP?
• We found SSL certificates for multiple domains but this is not suitable for us because in green box in Address bar will be visible only one company (this is suitable for one company that has multiple websites). So the only option is to buy different SSL for each different company and what is the best way to set IIS7 to support this?
• Can we host different websites (each with its own SSL) on same IIS7 webserver? What are our options?
