Roll out new sites fast?

Using 5.7

I find myself creating new sites with drupal and I follow some of the same steps each time. Download core and common modules (cck, views, pathauto, page_title, etc.) , create database, install drupal, install modules, create files directory, register cron job, create sites/all/modules and themes, install zen theme, create zen sub-theme. All in all, a lot of repetitive work.

I'd like to create some kind of "package" where I could just point to my server and have all this created. Any strategies to automate this or eliminate some steps?
