Install Wordpress MU in my hosting

Hi, I need a wordpress MU installed in my hosting account. The Hosting company is Locaweb, a brazilian hosting. Their control panel is a customized one, and is Brazilian Portuguese. To get the wordpress MU installed you must speak portuguese to understand how to use the hosting control panel. My hosting is a shared? Linux account. I also need you to configure the mod-rewrite to enable the blog to have several users, allowing me have URLs like these: <[login to view URL]> <[login to view URL]> <[login to view URL]> where peter, mary and bryan are users from wordpress MU. I need this done in 1 day. I think this is enough for the coder who knows how to install wordpress MU. Thank you.
