SQL 2012 SP1 Reporting Services for SharePoint (2013) - Install-SPRSService Not Available

Question

So, at this point, I've blown away an otherwise functional SP2013 + SQL2012SP1 multi-server farm trying to get this to work, only to end up with the same results. Irrespective of whether I install Reporting Services before or after the SP2013 server is in
a farm, SSRS does not seem to be enabled in the farm. I cannot add a new SSRS service application (the menu item does not exist); I cannot start the SSRS service on server (because it isn't here); I cannot execute the Install-SPRSService cmd in SP (yes, the
SharePoint) Powershell (PS comes back with this error:
Install-SPRSservice : The term 'Install-SPRSservice' is not recognized as the
name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is
correct and try again.
At line:1 char:1
+ Install-SPRSservice
+ ~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Install-SPRSservice:String) [],
    CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException
Quite simply, something's broken. I've followed a couple of detailed how-to's on technet and elsewhere... Right at the point when I should be able to create the SSRS service application, the wheels come off the cart. I've tried Import-Module'ing the SQLCMDLETS
and SQLPS PS modules...nothing... The strange thing is that after the installation of the SSRS, if I happen to go into the General Application Settings in Central Admin, I see a new item after Content Deployment:
$Resources:ReportServerResources,AdminReportServerGroupTitle; 
$Resources:ReportServerResources,ManageIntegrationSettings; | 
$Resources:ReportServerResources,AddTrustedAccounts; | 
$Resources:ReportServerResources,SetServerDefaults; 
When I uninstall, this goes away.
Greatly appreciate any suggestions you can offer because this is driving me crazy, and I have tried everything I can think of to get this going...

Make sure you are running SharePoint 2010 Management Shell not PowerShell.
Also make sure you are running SharePoint 2010 Management Shell with administrator privileges. Right click the icon and click, "Run As Administrator".
You must have installed "Reporting
Services add-in for SharePoint Products" on the server where you are executing "Install-SPService".
