Hello World!

My first post here is about some concerns/questions i have regarding website x5 evolution 12 and the services of domain registration and webhosting provided, before the company i work for buys it. I have 3 questions:

1. Can i use the domain name the company has bought from its ISP over 1 year ago, which is currently empty, as the domain name for the site i create with website x5? Or do i have to register a new one?

2. I would like to know (and believe me i have searched a bit, but did not find anything) what is the fee for webhosting after the 1 year free webhosting period.

3. I would also like to be provided with a link or some details on the procedure of using any other webhosting service. Does it include exporting the files regarding the site and uploading them via ftp to the webhost i desire, or is there some feature that supports the immediate upload to the webhost of my desire?

Thanks a lot beforehand.
