I suggest you do like I did... learn the basics first, no matter what your niche(s) is, because you'll need it in order to do anything... things like basic cPanel knowledge, uploading pages, etc... there are dozens of free tutorials on google that can teach you how to do all this.
Also, I would suggest to take a look at the link on my signature. It's very good for newbies and you can complement my video training with your tutorials online. I'm sure you'll be ready to get going in no time.
If you have any questions, you can post it here or feel free to send me a private message.
