How can I sell OEM Microsoft Software?? - how many computer can i install office pro 2003

I bought a CD package Microsoft Windows XP Pro and Office Pro 2003 OEM version of an online store. Both XP and Office license is unlimited, which means you can install on any computer, as many computers as I want. My question is, how can I copy them and sell them to people? What kind of permit or license should I?
