I know this is a Noob question, but one I have been stuck on for a while.
My hosting provider (hostgator) would love to install any script for me

. That is great if you only want to work on one site and not interested in knowing how to manage a website- and in my case 4 domains.
I am bored with blogging software right now wp, drupal and joomla and want to work on something that will actually make me a small income to start. I know im not the typical blogger, because I don't like writing everyday... database management and the backdoor operations of keeping up a website is what i am stuck on....
I will be back in college next month

and will not have the time I have right now, and would like to get at least one website started, and not waste my domains, parked making someone else money.
Any have a guide to installing a website script on a Domain using Filezilla? thanks in advance.
I should also add. I am not able to afford hundreds of dollars worth of software. example Dreamweaver or Photoshop
