Automatic site setup with powershell throws several errors - powershell

Question

first and foremost I am NOT a Powershell dev so I'm a little over my head here, if this was BASH it would have been done by now....
I'm getting several errors that I don't really understand the what or why of,
I believe that maybe $vars cannot be interpreted in the way that I am trying to use? idk...
If someone WITH powershell knowledge could lend an assist and educate this poor linux guy, I would be very grateful...
I would expect this to register and load a new (empty) site with IIS based of the input params provided.
Here's my PS1
# --------------------------------------------------------------------
# Define the variables.
# --------------------------------------------------------------------
Param (
[string]$InetSiteName = $( Read-Host "Site Name" ),
[int]$InetSitePort = $( Read-Host "Site Port" ),
[string]$InetPhysPath = $( $env:SystemDrive + "\inetpub\wwwroot" )
)
Import-Module "WebAdministration"
# --------------------------------------------------------------------
# Check for empty.
# --------------------------------------------------------------------
if(-not($InetSiteName)) { Throw "Site name cannot be empty..." }
if(-not($InetSitePort)) { Throw "Site port cannot be empty..." }
if(-not($InetPhysPath)) { Throw "Path name cannot be empty..." }
# --------------------------------------------------------------------
# Configure and register.
# --------------------------------------------------------------------
New-Item IIS:\Sites\$InetSiteName -physicalPath $InetPhysPath -bindings #{ protocol="http";bindingInformation=":"+$InetSitePort+":"+$InetSiteName }
Set-ItemProperty IIS:\Sites\$InetSiteName -name applicationPool -value BenAPI
Start-WebSite $InetSiteName
# --------------------------------------------------------------------
# Run.
# --------------------------------------------------------------------
$webclient = New-Object Net.WebClient
$webclient.DownloadString("http://localhost:$InetSitePort/");
$ie = New-Object -com InternetExplorer.Application
$ie.Visible = $true
$ie.Navigate("http://localhost:$InetSitePort/");

Answer 1

This is because "WebAdministration" module is not getting loaded. Run Powershell as Administrator so that "WebAdministration" module gets imported successfully.
Then Go to location where you have saved the script to run the script
PS C:\> cd 'C:\Users\jDaniel\Documents'
PS C:\Users\jDaniel\Documents> .\iis-site.ps1
There is a step to step guide Here - how to create Web-Sites, Web Applications, Virtual Directories and Application Pools in powershell.

Answer 2

This is how I create a new site:
New-WebSite -Name $InetSiteName -port $InetSitePort -id 555 -PhysicalPath "$InetPhysPath" -HostHeader $InetSiteName
if you need more binding you can use:
New-WebBinding -Name $InetSiteName -Port $InetSitePort2 -HostHeader $InetSiteName2

Answer 3

Looks like the real answer was that I didn't have a real pool created, here's my updated code...
