WHMSonic Shoutcast Admin Pro

i'm still not too sure how to put all this together,
And im starting to feel stressed out

I think i need a dedicated server with cpanel/whm installed on it
before i can install whmsonic and start selling radio streams with hosting right?

How much is this gonna set me back if i want to create a lot of accounts on one sever,
I am aware that you should only put so many accounts on one server.

I want to be able to offer the extras to the users so if they
are not using their account for live shows they can use the auto
dj features plus they'd have their web space for uploading audio.

And all the good stuff that comes with those features.
An example of what i'd like to offer is on sleepy engineers.

I just don't know if i have to get all this seperate and put it
on a dedicated server mysellf or if there's servers ready with
all this installed and ready to use.

And i don't have a lot of cash to start out
Im thinking 100$ per month to start with.

I like cast control's features, but i've only used whm/cpanel before, for setting up web hosting accounts.

Most reseller packages put me off it's never really my own service.
