Yeah that has to be manually done on your domain registrar or say cPanel where you use the Domain hostnames and then point it to the IP.

Not sure what you mean you can use a hostname for the server control panel but that's not part of Blesta or do you mean they can have a hostname for their IP, as that's normally the user's responsibility.

Thnx! Luv u! ?

You could do either option, I believe most commonly you would link the order buttons to the purchase link but with blesta the choice is yours... For example you could dynamically load each package price from blesta using the api and display it on your site so its always correct and up to date without having to adjust html pricing if package prices change.
If you don't already have a website or a designer you could always look on themeforest or such places for a theme and easily customize it to your needs. Plugins such as Blesta.Store's BlestaCMS will allow you to take your billing platform even further, fully integrating your website and blesta together into one. 

You only get Blesta with Blesta, which is the billing system only. If you want a website you need a HTML website. That or wordpress or another CMS system.

You can use blesta cms from mike . It will do the job .
I want suggest also cms pro from blesta addons but i dont know why is not released to public, i use it and is another plus for blesta .
