Make a Linux server for PODCAST

I’am part of another group of pepople: Redirecting...
We have started a podcast (out of life POD): ‎Out of Lives i Apple Podcasts

We started out with putting it on soundcloud, althoug we now have to pay to keep it that way. So i’m trying to make a hosing web server for a RSS feed with linux using this guide:

Is there any tips/tricks for making such a thing. I use derbian 7 as my distro althoug a have to admit i’m a noob when it comes to this stuff, but are the guide good?? Anyone who used it?
Also of you know another way to have a podcast on itunes for free plz let me know =)
I wonder as well how fast internet you need, i have abaut 50 down 20 up?

Also i would belive this belong here and not under the linux chategory?

Haha you reviewed your own podcast on the iTunes page
