jgrispa yeah I wouldn't worry about automating things just yet. Since you're just learning how to be a sysadmin and run your own hosting company on top of design business, that's too much to be also learning a complicated billing platform like whmcs and getting into the shit of automation and selling blindly to the public. Doing everything yourself manually can be sold as a positive too, giving clients a "white glove" setup, lots of small companies do that.
Search through the forums here, there's a ton of useful info about pretty much everything, including optimizing your servers for php/Apache/MySQL.
