Change Magento Store URL

This project is to change the URL of a live Magento store. For example change from [login to view URL] to [login to view URL] The second part of the project is to remove [login to view URL] from product pages of the new url for example Instead of [login to view URL] it should be [login to view URL] Like I said, this is a live Magento store, nothing else in the site should be changed except the URL. The site is currently hosted on a [login to view URL] Dedicated server. I looking for someone who can do this affordable and immidiately.
