re-install windows xp pro, outlook exchange account etc.

I need someone to format the disk and re-install windows xp pro, outlook exchange account, active directory and reconnect to the Windows SBS and ISA server. It is a Dell inspiron 9200 laptop. I will back up the data on an external hard drive and I will be here throughout the install to follow your instructions or to let you log into the server or through any other pc using teamviewer. We have done this many times before so it's not a problem if you know what you are doing.
