Do you have any web hosting provider yet? I host with Bluehost as they offer a one click install for Wordpress which I use for all my affiliate sites like this one: http://freeandalmostfreebooks.com/books/ Which kind of runs itself now.

For full disclosure: If you want to take a look at self-hosting on Bluehost my affiliate link is http://bluehost.com/track/newspowered/ which means if you end up using them they will pay me. (You would pay the same regardless of how you sign up with them.) Out of interest I just checked how long I've been hosting with them and was a little shocked to find my first order was on Aug 23, 2007, so over ten years with them.

You can host hundreds of websites on just one account if you need to, they're great for experimental projects.

Is there anything specific you need help with?
