Upgrade drupal 4.5(?) to latest

I would like to pay someone to upgrade my drupal installation from 4.5 to the latest. I've tried to do it on my own but the updater doesn't seem to work completely the way it should and I realize that its a pretty big task to upgrade such an old install. I'm not really using any big complicated modules or anything custom. I would like some quotes to perform this task. This would need to be done on a test site first so that the site editors can test it out and make sure the functions we use still work and then the upgrade would need to be done at night or on a weekend. Please contact me if you are interested in doing this.
