Check username availability on hotmail.com

I need a software that will be able to check an imported list of usernames to see if there are available to be registered as [login to view URL] email addresses. For example, i import: [login to view URL] ---------- bob @ [login to view URL] d928188fkasj197c @ [login to view URL] george @ [login to view URL] nick @ [login to view URL] x927615fkzu927fsd @ [login to view URL] Software should check every username to see if it is available to be registered, or it has been already registered, and it can't be used. It should be able to display and export both available and already registered usernames. For example: [login to view URL] -------------- d928188fkasj197c @ [login to view URL] x927615fkzu927fsd @ [login to view URL] [login to view URL] ------------------ bob @ [login to view URL] george @ [login to view URL] nick @ [login to view URL] It should be able to run on background and be fast. It also should be reliable. In case a username can't be checked due to connection problems, it should retry to check and not falsely consider it as not available to register. Checking if a username is available to register is a very easy procedure to do manually, if you enter them one by one on the register page, but it is time consuming. As far as i know there are no limits on checking. Please only bid if you understand exactly what i need and if you are sure you can provide it. Thank you.
